Hi, I am suffering from sciatica issue, 3 weeks back I had severe back pain later which is currently not there, but nowadays I get numbness in my left leg when I sit, the movement I change my sitting posture immediately I starts feeling relax. I do daily stretching exercise and yoga. I have started attending my office regularly. But due to numbness I get irritation feeling. Please let me know how long will it take to get cure. Or what action do I need to take immediately for further treatment.
