@judyem, Hello Judy. I have no answers on your rash. Hopefully it will subside soon. If it does persist, you may want to have it biopsied for MAC. In rare instances, it can spread to your skin. I don't mean to alarm you, it most likely is not that, but you should be aware. I feel for you, there is nothing worse than persistant itching. I got terrible hives from a sulpha medication once and thought I would go insane from the constant, intense itching over every square inch of my body. You can try taking a bath with one cup vinegar and one cup Epsom salt. Soak awhile. Those two things together draw toxins out of your body and soothe the skin. I do that occasionally; it is very refreshing if nothing else. I hope that you can still manage to enjoy the holidays, BIG HUG!
