@dsteede, I also have polymyalgia rheumatica (PMR) but it is currently in remission. I've had two occurrences of PMR. The first one lasted a little over 3 years and the second one about a 1-1/2 years. Both times my rheumatologist was concerned that I might have GCA and would ask me about tenderness in my scalp and temples but fortunately I did not have GCA. You mentioned doing some research which caused you to be a little concerned about the possibility of GCA. The following sites which you may have already seen do mention jaw pain associated with RA in case you didn't already know about it.
