I'm worried about my right foot. The joint at the bottom of my big toe on my right foot has been excruciatingly painful for months (like to the point of driving me to tears). I'm currently taking diclofenac and the pain has been reduced to more of a dull ache, but the joint is incredibly inflamed and now is looking deformed. It looks very swollen. Think I might go back to my GP about it. I'm worried that it's more rheumatoid deformity than just inflammation. However I have a negative RF and it's only in my right foot where I thought RA affected both sides. Anyone else have anything like this? It's been inflamed like this for a couple of weeks now and I think it's getting worse.
