I'm 49, was diagnosed with RA in March 09 with an RF of 169, so along with my symptoms, which were bilateral (both sides) pain in my joints, severe fatigue and pain that was worse in the morning but got better as the day progressed, along with swelling in my fingers and the inability to make even close to a fist in both hands, and a truckload of bloodwork, I was diagnosed with RA.
I'm no doctor, but with your symptoms, I would think about getting a second opinion from another rheumatologist. I've heard that you can have a slightly elevated RF and NOT have RA, but from your other symptoms, I would get a second opinion. I can't tell you if you have RA or not, and hopefully you don't, but those symptoms sound pretty suspicious. Good luck !!!
