Hi Dr, I have been facing pain on my lower back intermittently since three months as i had to work for 13-14 hrs continously. But though i am taking breaks in between and doing suryanamaskar pain is still same. Its bothering me now ?is it is severe ? What tests do i need to under go?is it is a common pain can be healed or something serious. I never had it before its past few months only. Thanks in Advance..
