I have lower right lumber pain. Last 1 month, I feel something stuck inside my muscles and I can not sit and drive otherwise it will increase pain. I do not know doc said its normal pain. But its different I do some exercise day and put ointment as well but it couldn't down intensity of pain. When stretched my back like some exercise I feel like my muscles got stuck and it can not stretched. I do not what to do. Please advise any med or exercise or any stuff that I can I buy.
