Sciatica and pain after running
03/10/2026IN BRIEF
| Sciatica is pain that can radiate from the lower back or buttock down to the leg, sometimes accompanied by tingling, numbness, or weakness. In Terrebonne, an assessment helps to examine the pathway of symptoms, function, and possible lumbar causes in order to discuss suitable options. Progressive weakness, a recent foot drop, loss of bladder or bowel control, or numbness in the saddle area requires urgent medical evaluation. The TAGMED Clinic is located at 1150 Lévis Street, Suite 200. |
Sciatica in Terrebonne: nerve symptoms not to be underestimated
Pain that starts in the lower back or buttock and radiates down the thigh, calf, or foot may be accompanied by tingling, numbness, or weakness. These signs warrant an evaluation, especially if they worsen or limit walking.
At the TAGMED Clinic, located at 1150 Lévis Street, Suite 200, in Terrebonne, the evaluation takes into account the trajectory of the pain, sensitivity, strength, function, and available exams. The proposed plan depends on your situation; an MRI image alone is not sufficient to confirm the cause of the symptoms.
Consult urgently in case of loss of bladder or bowel control, numbness around the perineum or saddle area, significant or progressive weakness, or recent onset of foot drop. These signs require immediate medical evaluation.

Pain that starts in the lower back or buttock and radiates down the leg may be related to irritation of a nerve root. Tingling, numbness, or weakness may also occur. In Terrebonne, an evaluation allows examination of the pathway of symptoms, their effect on your activities, and signs that require rapid medical guidance. Sciatica describes a set of symptoms, not a specific disease. Pain may move from the lower back to the buttock, thigh, calf, ankle, or foot. Some individuals feel a burning sensation, electric shocks, or sharp pains. Others may notice tingling or loss of sensitivity. The pathway of symptoms provides clues, but does not confirm the cause by itself. Irritation of the L4 root may affect the front of the thigh or the inner side of the leg. An issue compatible with L5 may manifest on the side of the leg or the top of the foot. Symptoms associated with S1 may reach the back of the calf or the outer edge of the foot. These indicators must be interpreted alongside examination and the entirety of your situation. Nerve pain may be sharp, burning, or felt like an electrical current. It can intensify when sitting, during walking, or after an active day. To learn more about an electric current sensation in the calf, check our article dedicated to this symptom. Numbness or reduced sensitivity also deserves particular attention, especially if the symptom spreads or worsens. Deep pain in the buttock radiating to the thigh can have several causes. You can read our page on deep buttock pain and radiation to the thigh. A new difficulty in lifting the foot, walking on heels or toes, climbing stairs, or maintaining balance may indicate nerve function impairment. Significant or progressive weakness should not be taken lightly. A dragging foot or a collapsing leg requires prompt evaluation. Consult an emergency medical service without delay if you observe a recent loss of bladder or bowel control, numbness around the perineum or saddle area, or significant and rapidly progressive weakness. Significant symptoms in both legs, fever accompanying low back pain, a major trauma, or unusual general deterioration also require swift attention. These signs should not wait for a routine consultation or a care session. To better understand the signs to watch for, consult our guide on evaluation and management options for sciatica in Terrebonne. A hernia or disc protrusion can irritate a nerve root if its position matches the side and pathway of the symptoms. Foramen narrowing, lumbar stenosis, or changes related to disc degeneration can also contribute to pain. The hip, pelvis, muscles, or a peripheral nerve issue may sometimes produce similar symptoms. An abnormal image on an MRI does not alone prove that it causes your symptoms. The professional correlates the imaging report, the painful side, the neurological exam, and limitations in your activities. If pain persists in the heel, also check our page on persistent pain in the heel. Pain that intensifies in the evening is addressed in another article on symptoms that worsen at the end of the day. The first consultation allows for clarifying the onset of symptoms, their trajectory, and activities that aggravate or relieve them. The evaluation may include observation of walking, mobility, strength, and sensitivity. Reflexes and other relevant factors may also be examined. Bring your reports or imaging tests if available. At the TAGMED Clinic in Terrebonne, the plan is discussed based on the results of the evaluation, your functional goals, and options that may be considered. Conservative approaches, including motorized neurovertebral decompression for some patients, are not suitable for everyone. Traction is not systematically recommended for all low back pain with or without sciatica. Benefits, limitations, and re-evaluation criteria must be explained before considering it. If the chosen approach does not lead to measurable improvement in pain, walking, or sitting tolerance, the plan should be re-evaluated. A consultation does not replace a medical diagnosis. A referral to a physician may be necessary depending on the symptoms. The TAGMED Clinic is located at 1150 Lévis Street, Suite 200, Terrebonne, QC J6W 5S6. If pain radiates down your leg, if numbness persists, or if your function changes, an assessment can help determine the appropriate next steps. Check out the services related to sciatica treatment in Terrebonne. Pain that hinders driving or limits the time spent sitting can also have a significant impact on daily life. Read our article on sciatica in Terrebonne and difficulty driving for long periods. For persistent symptoms, also consult our resource on chronic sciatica in Terrebonne. Dr. Sylvain Desforges, B.Sc., D.O., N.D., osteopath, is the founding president of TAGMED and the ACMA association. His practice focuses particularly on chronic pain of the spine, lower back pain, and symptoms consistent with sciatica.

Recognizing Nervous Symptoms
Sciatica generally describes pain radiating to the buttock, thigh, calf, or foot, sometimes related to the irritation of a lumbar nerve root. It may present as a burning sensation, electric shock, tingling, or loss of sensitivity. However, leg pain is not always of nerve origin: the hip, muscles, or other structures may produce similar symptoms.
Observe the Path and Function
Note the affected side, the areas where the pain radiates, and the activities that change it, such as walking, sitting, or working. Pain projecting to the front of the thigh, the top of the foot, or the back of the calf may provide clues, but the path alone does not confirm an affected root. Strength, sensitivity, walking, and reflexes should be interpreted as a whole.
A new difficulty in lifting the foot, walking on heels or toes, climbing stairs, or stabilizing the leg deserves particular attention. If weakness appears or progresses, seek rapid medical evaluation rather than waiting for the symptom to resolve on its own.
Sciatica in Terrebonne: why the affected root changes the pain path

When to Seek Urgent Help
Certain signs should not wait for a routine appointment: loss of control of the bladder or bowels, numbness of the perineum or “saddle” area, significant or rapidly growing weakness, or recent appearance of foot drop. Notable bilateral pain, fever, significant trauma, or unusual general deterioration also require appropriate medical evaluation.
In the presence of these symptoms, contact a medical service or emergency department immediately. Do not attempt to replace this evaluation with a manual therapy session or mechanical treatment.

What to Expect During an Evaluation in Terrebonne?
At the TAGMED Clinic, at 1150 Lévis Street, Suite 200, Terrebonne, the first consultation aims to clarify the history of symptoms, their path, and impact on walking, sleeping, work, and daily activities. The examination may include assessing mobility, strength, and sensitivity. Bring your MRI reports or other tests, if you have them: their significance depends on their alignment with clinical signs.
A herniation, a protrusion or a narrowing observed in imaging does not, on its own, prove that this anomaly explains the pain. The proposed plan must take your situation into account and present measurable objectives, limits, and re-evaluation criteria. Maintaining tolerable activities and appropriate exercise can be addressed; any conservative approach must be re-evaluated based on your progress. Motorized traction, if applicable, is not suitable for everyone and does not guarantee any results.

Sciatica in Terrebonne: Nerve Symptoms Not to Underestimate
Pain that radiates from the lower back or buttock down to the thigh, calf, or foot may be consistent with irritation of a lumbar nerve root. Tingling, a burning sensation, numbness, or weakness may also accompany the pain. These signs deserve special attention, especially if they are new, worsening, or limiting walking and daily activities.
The testimonials below are illustrative narratives created for informational purposes. They do not describe real patients and do not allow for a diagnosis.
Illustrative Narrative — Pain Down to the Foot: “The pain started from my buttock and went down the side of my leg to above my foot. I also had tingling. During the consultation, I was explained that the path of the symptoms needed to be correlated with the examination of sensitivity, strength, and function.”
Irradiation towards the foot or toes can provide useful clues, but the path of the pain is not enough to confirm which nerve root is involved. The profiles associated with L4, L5, or S1 are clinical markers to be interpreted with other signs and the context of each individual.
Illustrative Narrative — Numbness and Walking: “My leg would become numb after a few minutes of standing, and I had to stop. I understood that it was important to mention the duration of walking, the positions that triggered the symptoms, and any changes in strength.”
An evaluation may take into account the onset of the pain, its side and distribution, sensitivity, strength, walking, and difficulties at work or during sleep. If an MRI or other examinations are already available, their results can be compared to the symptoms. However, a visible anomaly on imaging does not, on its own, prove that it is the cause of the pain.
Illustrative Narrative — Weakness of the Foot: “I was having increasing difficulty raising the front of my foot. I was advised not to wait for a treatment session and to seek a medical evaluation quickly.” New or progressive weakness, a leg giving way, or foot drop requires prompt attention.
Consult urgently in case of recent loss of bladder or bowel control, numbness in the saddle area or perineum, significant or rapidly progressive weakness, marked neurological symptoms in both legs, fever, or pain following a major trauma. These signs should not wait for a routine consultation.
Possible causes of the symptoms include a herniated or disc protrusion, foraminal narrowing, or lumbar stenosis. Pain originating from the hip, pelvis, muscles, or another nerve can also resemble sciatica. The choice of management options thus depends on evaluation, safety, and functional objectives.
At the TAGMED Clinic in Terrebonne, located at 1150 Lévis Street, Suite 200, the evaluation aims to specify the path of the symptoms, examine neurological signs and function, and then discuss conservative options that may be suitable. The proposed approaches and outcomes vary depending on the situation; no method guarantees relief or replaces medical advice when it is necessary.
Medical Warning: this information is educational and does not replace a consultation, diagnosis, or treatment by a licensed health professional. Manual or functional approaches do not constitute medical acts. In the presence of emergency signs, seek a medical evaluation without delay.
Sciatica in Terrebonne: Nerve Symptoms Not to Underestimate
Pain that starts from the lower back or buttock and radiates down the thigh, calf, or foot may be consistent with irritation of a lumbar nerve root. It may be accompanied by tingling, burning, electric shocks, or numbness. These manifestations are sometimes grouped under the term sciatica, but this word does not alone denote a specific cause. Similar pain may also be related to the hip, pelvis, muscles, or other health issues.
At the TAGMED Clinic in Terrebonne, located at 1150 Lévis Street, Suite 200, the evaluation aims to better understand the distribution of symptoms and their effect on daily activities. Walking, sitting or standing, sleeping, and working provide important benchmarks. The examination may also focus on mobility, strength, and sensitivity. These observations help determine if further medical evaluation or referral to another professional is indicated.
The path of pain provides clues, without confirming a diagnosis on its own. Some patterns compatible with an L4 involvement manifest more towards the front of the thigh or the knee; those associated with L5 may affect the side of the leg and the top of the foot; an S1 involvement can project towards the back of the calf or the outer edge of the foot. No area of sensitivity, muscle movement, or reflex is sufficient on its own to establish the cause.
A herniated disc, a protrusion, a decrease in disc height, or foraminal stenosis can sometimes irritate a nerve root. However, an abnormality on an MRI does not necessarily explain the symptoms: it must be related to the painful side, the examination, and the function. If you already have imaging or a report, these documents can help situate the results in the context of your situation.
Some signs require special attention. A recent loss of control of the bladder or bowels, numbness in the saddle area, significant or rapidly worsening weakness, or the appearance of a foot drop warrant urgent medical evaluation. One should not wait for a routine consultation or treatment session. A fever, major trauma, or unusual deterioration in the general condition should also be reported to a healthcare professional.
When the situation is stable and no alarm signs are noted, different conservative options can be discussed based on the evaluation. Information, maintaining tolerated activities, and a gradual return to movement are often elements to consider. Manual or instrumental approaches may sometimes be integrated into an individualized plan, but they are not suitable for everyone, and their results vary. Motorized traction, for example, is not systematically recommended for all low back pain with or without sciatica; its utility must be assessed on a case-by-case basis, with measurable objectives and re-evaluation.
Dr Sylvain Desforges, B.Sc., D.O., N.D., osteopath, is the founding president of TAGMED clinics and the ACMA association. His background focuses on managing chronic pain, particularly spinal pain, as well as the reasoned integration of technologies such as neurovertebral decompression, laser, and shockwaves. In Terrebonne, the goal of the consultation is to clarify symptoms, explain the possibilities and limitations of the considered approaches, and agree on follow-up criteria tailored to the function and needs of the person.
The information presented is educational and does not replace a consultation, diagnosis, or treatment by a physician or another authorized healthcare professional. Osteopathy and manual approaches do not constitute medical acts. In the presence of emergency signs or progressive weakness, seek appropriate medical care promptly.
In Terrebonne, pain that radiates down from the lower back or buttock to the thigh, calf, or foot may be accompanied by tingling, numbness, or weakness. These nerve symptoms should not be trivialized: their pathway, progression, and effects on walking or daily activities deserve appropriate evaluation, especially if they worsen.
Sciatica refers to a set of symptoms that may be associated with irritation of a lumbar nerve root or the sciatic nerve. The pain may take the form of a burning sensation, pulling, or an electric shock in the leg. It may also be accompanied by tingling or loss of sensitivity. To better recognize possible manifestations, consult this guide on the symptoms, causes, and relief of sciatica or information on the sciatic nerve.
The trajectory of the symptoms provides clues, but is not sufficient to establish a diagnosis. Pain in the calf resembling a cramp, pain that radiates below the knee, or a foot pain without low back pain may sometimes be compatible with nerve irritation. However, pain in the leg may also originate from the hip, pelvis, muscles, a peripheral nerve, or another cause. Resources on intermittent or constant pain and this article for understanding the symptoms and causes of sciatica can provide general guidelines without replacing a consultation.
The evaluation takes into account the history of the symptoms, their side and distribution, but also sensitivity, strength, walking, and tolerance to sitting and standing positions. New or progressive weakness, difficulty lifting the foot, or a leg giving way warrant prompt attention. Nerve territories such as L4, L5, and S1 serve as landmarks, but no painful path, clinical test, or reflex confirms the cause on its own.
An MRI or other imaging test may be useful depending on the context, but its results must be correlated with the symptoms and examination. A hernia, protrusion, or visible stenosis does not automatically explain the pain: some abnormalities are present without causing symptoms. Therefore, management options depend on the profile and may include maintaining tolerated activities, adapted exercises, and, for certain selected individuals, conservative approaches reassessed based on their functional effect. To learn more about the services and evaluation, visit the TAGMED clinic’s page dedicated to sciatica or information on sciatica treatment in Terrebonne.
Some signs necessitate a urgent medical evaluation rather than a routine appointment: loss of urinary or bowel control, numbness in the saddle area or perineum, significant or rapidly progressive weakness, recent foot drop, pronounced symptoms in both legs, fever, or pain following major trauma. If any of these signs occur, do not delay in seeking medical assistance.
For pain radiating into the leg, TAGMED Clinic offers consultations at 1150 Lévis Street, Suite 200, Terrebonne, QC J6W 5S6. The first visit may serve to clarify the picture, examine function and neurological signs, consider already available exams, and discuss appropriate options. The information presented here is educational and does not replace a diagnosis or advice from an authorized healthcare professional.
