Sciatica usually describes pain or other symptoms that travel along the path of the sciatic nerve, often from the lower back or buttock into the leg. The word describes a symptom pattern rather than one single cause, which is why assessment matters.
Common symptoms people describe
Symptoms may include pain that travels into the buttock, thigh, calf or foot, pins and needles, altered sensation or a feeling of weakness. Some people have significant back pain as well, while others notice mainly leg symptoms.
Sitting, bending, coughing, walking or standing can affect symptoms differently from person to person. That pattern helps guide assessment.
Why a scan does not tell the whole story
MRI findings such as disc bulges can be relevant, but they do not automatically explain every symptom. Clinical assessment also looks at strength, sensation, reflex-related concerns, movement tolerance and how symptoms change with positions and activity.
A physiotherapist should combine the report with the person in front of them rather than treating the scan alone.
What physiotherapy may focus on
A rehabilitation plan may include education about comfortable positions and pacing, graded walking, mobility work, strength exercises and a gradual return to daily tasks. The exact exercises depend on what the assessment shows.
For irritable symptoms, the first goal may simply be finding tolerable movement. As symptoms settle, the focus can shift toward strength, endurance and confidence.
Staying active without forcing symptoms
Complete bed rest is rarely a useful long-term strategy for routine back and leg pain. At the same time, aggressively pushing through severe symptoms is not a badge of progress. The useful middle ground is graded activity that your body can tolerate.
Short, frequent walks or modified activities may be easier than long sessions at first. Your therapist can help set a starting dose.
When sciatica needs urgent medical attention
Seek urgent medical care for new loss of bladder or bowel control, numbness around the saddle region, rapidly worsening leg weakness, major trauma or other severe new neurological symptoms.
These are not situations to manage only with home exercises.
