I am a newly diagnosed Seropositive 50yo female. After years of what I thought was osteoarthritis pain, I sought treatment when I started experiencing excessive swelling in my feet and knees, and extreme chronic back pain. My 3rd dose of MTX is Sunday, and the only big change has been less swelling but a HUGE increase in all those same joints popping with any position change. I am curious if it is a by product of rapid reduction in swelling, does it improve over time? Its aggravating at its worst, but makes me wonder why it started. Thoughts?
