I think I may have discovered the reason for my ear pain when taking hearing tests.. A month ago I was diagnosed by biopsy with Giant Cell Arteritis, a rare but curable disease, which may cause ear pain as well as jaw pain and other problems. My audiologist has lowered the volume in my aids, which helps considerably, and I can adjust them higher for short periods. At this point I need to focus on recovering from GCA, and am glad to have the help of a audiologist with realistic expectations. This forum has been very helpful.
