Doc, I have been suffering from lower back pain since 3-4 years now. It is not persistent. If a different kind of pressure is faced by my back, the pain starts and remains for some days. Last time it started on 30th June and was there for around a week. Now again 2-3 days back it has started. I am really clueless as to what has happened since even the Xray shows everything normal. Please help me and give me some advice. Any exercise? Or how should I have my sleeping posture? I won't be able to pay money and ask more questions. So please do try to give maximum help possible in your reply. I seriously need help. Looking forward to your kind revert. Thank you.
