I am 38-year-old and have sciatica (lower back pain). I was active in my college days and worked out regularly. Now I cannot do any exercise except yoga. Even if the yogasan goes a little wrong the back pain & sciatica pain starts and lasts for 20 to 25 days. I want to do crunches push-ups weights etc. What should I do? Answered by physiotherepist Shiphrah Lakka From your question your history is not clear but it looks like you’ve had sciatica for a while now. Sciatica usually responds to brief periods of rest and limited activity during flare-ups. You must re-start
