Arthritis in my back

Finally made it to the nuerogist yesterday after work. The muscle spasms I have been having is do to arthritis. I never heard of such a thing. I could try physcial theraphy, but he didn't recomend it. PT sometimes can cause more damage than good. I could try a chiropractor, but again it may cause more damage than help me, plus it's not covered well by our insurance so I won't try this. Another option is epidural shots, which he is nervous about because I'd have to be off my coumidin, which isn't so great of an option. Right now were going to do Vicidin for pain. If I don't like that, we'll try other pain meds. He doesn't even care if I become atticted because really I need something for pain, that's not going to just go away on it's own.
