I thought it might be low oxygen to my skin . The stream from the shower might put enuf pressure on the skin to push oxygen away. That might be what your doc called contact reaction . However , I do recommend that ointment . It is kind of greasy. I hope we get more comments. My doc just looks confused when I tell her about it . Of course I am not peeling when I see her . I put a heat pad on my back for lung pain last night . It caused me the worst itching. I ‘m watching it today to see what more it might do . Thanks for your comments . Blessed Be, Crystal
