After visiting 4 doctors, FINALLY I found one who recognized immediately what the rash was. Actually it is hives. He spent about 20 in The room with us, reviewing length of time this has been happening, how long it last each time, explaining the causes, and recommending solutions. His bedside manner was terrific. A very warm and informative doctor. For once I wasn’t another dollar bill sitting in the chair. I wasn’t dismissed as a trivial problem. So happy to have found him.
