And got one helluva rash where I had the bandage covering a small, yet healing wound not quite under the arm. Nothing I did would relieve the rash other than temporarily. Unaffected skin touching it just made it worse.
It turns out my not tossing out my old dance gear, especially my dance tops (choli) came in handy. The close fitting on the arm, and more importantly, on the torso, preventing rash from getting irritated by skin touching skin where the rash is. Wore one under my jammies last night, and have another one on now. Ever so much better.
