Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query Now it seems you have already tried all the pain killers you could get your hands on. Now this may sound preachy but that is very wrong. Also from the query, I am uncertain what dose and frequency you were using for the tablets. I would suggest that we first evaluate the cause of your problem rather than give medicines blindly. I would like to know if you have any other symptoms, like say pain in the legs/arms, tingling.numbness of the legs/arms. I would suggest you get an X ray LS spine AP and Lateral. Ideally I would have preferred an MRI, but since I cannot examine you and you have not met a doctor yet, I would suggest get an X ray. And according to its report we can decide if we need to go for an MRI I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. Best of luck. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this)
