How long does exercise therapy take to work for sciatica?

Sciatica involves irritation of a nerve root in the lower back, so symptoms may travel through the buttock and leg. A programme may combine gentle movement, trunk and hip strengthening, and advice on activity. Early progress can mean walking, sitting, or changing position more comfortably rather than complete symptom disappearance. Nerve-related sensations such as tingling may settle at a different pace from back or leg pain.

Follow the dose and technique your physiotherapist gives you, and increase activity in small steps. A mild, short-lived increase in symptoms can be useful feedback, but stop an exercise that causes spreading leg pain, new weakness, or symptoms that remain worse afterwards. Keep a simple record of walking tolerance, sleep, and leg symptoms so the plan can be adjusted. Read more about [Exercise Therapy](/treatments/physiotherapy-and-rehabilitation/exercise-therapy/).

Arrange a clinical review if symptoms are worsening, strength is changing, or progress has stalled despite following the plan. Seek urgent medical care for new loss of bladder or bowel control, numbness around the groin or saddle area, or severe weakness in both legs. These signs need prompt assessment rather than a change to home exercises.

Which movements should I prioritise, and which should I temporarily modify? How will we measure improvement in leg pain, strength, and walking? What should I do if symptoms travel farther down the leg after exercise?
