I meant it isn't at all "unusual" to test negative. :) Sorry, I'm typing with a splint on one finger. lol
It isn't at all to test negative for autoimmune diseases like RA and lupus yet still have symptoms. Are you seeing a rheumatologist or an orthopedic surgeon? It sounds like your doctor is willing to try a variety of pain relief techniques, which isn't always the case with some docs. if you aren't seeing a rheumie, ask for a referral, and also for a referral to a pain management specialist.
