I was diagnosed with RA in December 2010. I am on Meloxicam, Methotrexate & Prednisone. (plus a few other vitamin supplements)
Recently started having spasm/pains that kinda feel like an electrical shock that goes from my arm(s) down thru my fingers. Is this a common RA symptom? A medicinal side effect?
this isn't a typical RA symptom, but sounds more like perhaps a nerve is being pinched somewhere in your neck or shoulder area. I'd recommend that you speak to your doctor about this to get it checked out.
Not being a medical professional, I can't say for sure what is causing your electric shock sensation. But I can tell you from personal experience that before my RA was treated, I had a similar electric shock feeling which traveled from my forearm through my fingers on the palm side. I was diagnosed with Carpal Tunnel Syndrome but it was really the swelling from my RA which was putting pressure on the nerve traveling through the wrist. It was very, very painful at the time. It hasn't come back, though, once the methotrexate began to work.
