my arms are red, blotchy, and are a little warm. its only my arms, from just below the shoulder down to the mid forearm. ive also found out that they sting a little. especially when i try to cool them down with colder water. this has happened before, i took some benedril, and it went away eventually. but this is my second time, and i took benedril again but nothing much has changed. i haven t used any different detergents/perfumes or anything. just a little confused on what this is and wondering how i could treat it in a more helpful way? maybe a tip to cool it down without stinging? thank you x
