within 24 hours, I developed a painful Red raised rash under both of my arms. I put ice cold clean washcloth for short amount of time to ease the pain. I try to keep my arms raised as much as possible to dry the area. I have tried thin layers of coconut oil with no results. I have tried Lotrimin spray with little relief. the pain is so bad when my arms are down, I can't sleep, or anything else that requires my arms down. I am a large woman and have delt with heat rash in warm parts of my body but this has become unbearable. If you have any suggestions for me I would appriciate very much. Signed, painful
