How do I know is this is arthritis or not. Cause I'm starting to think it might not be. The blood tests and x-rays came back negative. Ever since I was small (about three) I have had chronic joint pain. At first they thought it was growing pains and pretty much ignored my pain, so I learned to deal with it. Then I stopped growing and the pain continued so finally at eighteen my mom beleived me, and we went to get tests done, they thought it was arthritis because we have a family history but the tests all came back negative. I've gotten tests done multiple times and all negative. There is a strange thing, I only seem to have the symptoms of chronic joint pain, no swelling, no redness or fever. Is there a test that I don't know of that could help me find out if this is really what it is?
