I have an implantable defibrillator (ICD). I had to get it after my shoulder was replaced and that night in the hospital I had a heart attack. It gives me afib now from time to time and they say that’s dangerous maybe, so just in case, and so on and so on. I’m not quite sure if it ever gave me a flare per se, but I do know that any time I get a major procedure done or there is any kind of body changes, my RA does NOT like it. It can react in a number of ways but usually I just won’t feel well for a few days or weeks. It is infuriating and frustrating, for sure, but as my mom tells me when I get down - “this too shall pass.” Please let us know if there’s anything we can do to help from here and hopefully today is a lower pain day. Keep on keepin’ on, DPM
