Juliana, I have both RA and fibromyalgia. I was diagnosed with FM last summer. It is hard to know where the pain is coming from, as I was told by my consultant that when you have both its very difficult to distinguish one from the other. I do know for definite that my foot problems are RA related, but my other pain, who knows????
I know thats not much help, but its probably best to read up as much as you can, and then discuss it at your next appointment. Sorry you have both, they do seem to go hand in hand quite often, as if an autoimmune disease isnt enough!!!!
