My name is amman I have posted a question about my lower back pain two weeks later and three doctors answer me. I am taking cure from from doctors but still not in good health. After relief of 4 to 5 days of week still pain is there? Is this is due ro mate with my wife? Or any else I am still in pain and no doctor is finding my problem. My x ray report is good. I feel pain in pelvic gridles and at end of backbone. What is the reason of this so I will avoid it.
