In most cases, sciatica is caused by a slipped disc. However, other spinal conditions, such as spinal injury, infection, or tumor may also cause sciatica. While the symptoms of sciatica often resolve with conservative treatment, more severe cases may require continuous physiotherapy or surgery. Physiotherapists use strengthening and stretching exercises to strengthen the spinal column and alleviate sciatic pain. In addition to this, low-impact aerobic exercises are also used to facilitate the recovery and help the patient regain their strength and mobility.
