Not knowing where you are posting from makes this advice a bit difficult, but . . .

Go to or get a referral to a Pain Center. They specialize in treating pain of various sorts, and are usually pretty good at what they do. My local folks shot two lots of Cortisone into the spaces between my lower vertebrae, where the pain was originating, and the cure has worked for about 9 months so far. This needs to be done by someone who knows what s/he is doing. My doctor had me on the table, sedated, using something like X-ray to tell exactly where he was shooting the steriod. These injections may need to be repeated every 6-12 months until your back and nerves get the message.

If your country doesn't do Pain Centers, get a referral to and work with a neurologist to determine what is causing the pain, and then follow his/her advice.
