The first time it happened, my doctor thought I had been bitten by a spider, but that was ruled out. Was put on Steroids, given a steroid
injection and an anti-itch cream. Happened several times that summer and we finally thought it was an allergic reaction to something used on a golf course. That seemed to be the only time it would happen, is after I played golf. Same treatment was given each time and it cleared up. Now it has started happening when I have been out in my yard.
