First of all, I want to let you know that you are not alone.
Secondly, it sounds like your back has taken quite a beating over the years.
*(Keep in mind I am a youngin [18] so things I say might not be perfectly right)*
However, is the Tramadol you are taking working for your pain at all?
I have 2 herniated discs in my back and I was prescribed tramadol and it did NOTHING at all for my pain. I was switched to Vicodin, and that did nothing either besides make me a little bit happy.
ANYWAY: My reccomendation, if your pain meds are not working, is to contact your doctor and tell him they are not working. If there is nothing they can do for your pain, the least they can do is mask it. Keep in mind there are serious side effects from certain narcotic pain medications.
You may find relief from Vicodin, seeing as how it is an opiate pain reliever, and Tramadol is not.
I can understand your depression because I feel the same. Im sure you feel helpless and the pain is probably unbareable as is mine, but my advice would be to tell your doctor and if he does nothing about it. Try seeing a specialist such as a neurologist, or a sports medicine doctor as was suggested to me. Even a pain specialist would be good. Just let him know that nothing is working out, and you are in need for relief.
I hope I helped some.
