Debbie - Ouch!!! I'm so sorry you are experiencing that. I don't have RA but, as you know, have been suffering with joint/tendon issues for quite some time now. Mine become really swollen, red, and warm. It's not fun and can be very painful so I can totally relate to how you are feeling.

Have you discussed this with your PCP? The tests are fairly simple blood tests and he/she can also refer to you a rheumy if you don't have one already. Hang in there and let us know how you are doing.
