"I have zero negative RA and was diagnosed about 4 years ago. I am 62 years old. I have tried several medications and am currently on Orencia. It has been working pretty well but recently I have been having random sharp pains intermittently in different joints . My ankle hurt yesterday for about 18 hours and then miraculously stopped- sore, but the sharp pain was gone today my right knee has the same issue- but only off and on for an hour etc. Am I going crazy or is this related to my RA ?"
