I've been on Enbrel for the past 6 months (and MTX for the past 3 years) for moderate RA. I'm doing better, but in April, I started having problems with really bad pain in my right shoulder, and my physiotherapist suspects that I'm having problems with a tendon in my rotator cuff. I'll be checking in with my Rheumatologist, but has anyone else run into a similar issue that was linked to their RA or being on Enbrel? There's no injury that occurred to explain what's happening.
