I appreciate your taking the time to come back to this. I’ve read quite a lot about PMR on the Mayo Clinic site, the Johns Hopkins site, and on the Arthritis Foundation site, and those readings brought me to GCA and the warning signs. I also have a friend who two years ago had GCA and did not act quickly enough. She has partial vision back in the affected eye, but it will never be normal again. She did not have PMR, but I know it can happen either way. Thanks again for caring and providing helpful information!
