Daphne I have experienced muscle pain in every part of my body, caused by RA. So yes it could be your RA. If it lasts more than a few days get checked out. Feel better soon🤗
I have that and had heart issues ruled out but it’s been a process. I’m currently seeing a physical therapist for a shoulder separation that I didn’t know I had. It’s been helping with that and the boney lump on a rib.
