The jaw pain is exactly as you describe...especially painful in the morning so if I try to eat a bagel before taking my prednisone I power through the jaw pain. It's only on one side...no tooth pain or mouth pain just the one jaw hinge. By mid day it improves. They did the artery biopsy on the opposite side. They said some Dr perform the artery biopsy on both sides to be as thorough as possible, but they felt since all clear one the side they performed the biopsy on...they are not planning to do the side where I have the jaw pain. I'm not on medicare yet (still on the fence about retiring as I try to wrap my head around how PMR will truly impact me once it's fully treated and stable), but my military retiree insurance has been super throughout all of the variations (total of 11) of MRIs CT scans and ultrasounds over the past 8 weeks to reach this PMR diagnosis...Hopefully if my rheumatologist recommends Kevzara, etc. they will cover it with little if any pushback. And so the journey begins...
