Just developed ra and will be starting tablets when I decide best day to start them. Only received them yesterday after meeting with the consultant for the second time but late yesterday I started to have muscle spasms in the top of my left arm and this morning i have had to miss work because i couldnt lift my arm to shower. This is a common problem i keep getting over the last few years but didn't mention it to the doctor because to be honest I hadn't had it for a few months. Does anyone else get this, feels like a trapped nerve and is it a symptom of ra ? Hope you are all enjoying the sun and I look forward to reading your replys.
