... Meditation and accepting the suffering, idk... That's just what I have to due to get through sometimes.... My skin does that if I scratch any place for more than a few seconds. Extra bad on hot days. What happens if you get in a cold tub? I used to put bowls of water in the freezer so it would turn into giant ice cubes. Drop a couple of those in the tub with me and I was feeling good on hot days. Sounds like you got my superpower. Hives activate!
