Sciatica pain with hip and knee pain. is walking good?

Evaluation: You should rest and see your doctor to be evaluated and may have CT of spine to find the cause so be treated.

Back pain: The answer depends on the anatomical reason for your discomfort. Sciatica in your age group is usually a phenomenon which occurs secondary to a small disk herniation. More often than not, supportive treatment in the form of physical therapy and a short course or pain medication will work but you have to be patient :) In short, yes walking and even stretching are good.
