Sudden joint and bone aches! And I'm in remission!

Hello everyone! So I've been in remission for a few yrs now feeling overall pretty great aside from mild anemia and fatigue. A couple weeks ago I started to have achy hands and feet that comes and goes from one day to the next. I'm also feeling it in my neck and lower back. No swelling or redness. I've been on Humira for 2 yrs and have had no flare ups. Could be the start of RA?
Any thoughts would be appreciated :))

I'm struggling with bad knee pain and swelling and my GI symptoms seem to be in remission. I'm still not sure if my knee is Crohn's related, but I suspect it is. Waiting forever for a doc appointment. I agree with Kazbern....with the humira on board, you should check it out with your doctor.
