RA can be tricky to diagnose - symptoms come and go, bloodwork wobbles up and down and at times, symptoms can mimic other conditions and if you are older, the tendency can be to diagnose osteo instead of RA. However, from a layperson's point of view, your symptoms sound like they could fit both kinds of arthritis. As well, it is quite possible to have rheumatoid arthritis without testing positive in your bloodwork -many RA patients have a negative RA factor (myself included). However, some doctors prefer having numbers show up on lab tests before they're comfortable making a diagnosis. I would recommend that you find another rheumatologist for a second opinion. I'm a big fan of trusting your instincts and if you feel that a diagnosis of osteo is not giving you the treatment that you need, keep trying. Doctors are people, too and sometimes, you have to meet with several before you find one that works for you.

In terms of pain meds, I'm leery of recommending anything specific if you have additional medical issues that may be affected by painkillers. Over-the-counter ibuprofen may help and there are a number of prescription anti-inflammatories that may work for you. However, you should discuss pain management with your doctor, who will be much better able to recommend something that won't aggravate other medical conditions. Is there a specific reason why your doctor hasn't prescribed painkillers or anti-inflammatories for you? Keep in mind that sometimes, we as patients get a little passive in a doctor's office and don't ask for what we need. When you have RA or osteo, it is normal to have to live with some degree of pain, but we can end up feeling like we have to just accept pain and forget to ask for help if it increases. If you have a lot of pain that significantly interferes with your ability to live your life, asking for stronger pain meds is reasonable.

Good luck!
