It’s a water allergy! There’s only like 30-50 cases in the world, at least reported cases so there’s not much known about it other than duration and that the skin touching liquid can affect it — it doesn’t matter the type, where, or temperature of the water the skin will form hives— mainly girls get the condition during or after puberty and that in some cases the condition can go away in months to years. Thankfully in my case I only itchy hives from my hips/torso up to my face most times, some people can’t even slightly sweat without breaking into painful hives all over their body. I’ve had this condition since 2022 but only recently began actually researching it. Fun fact this condition is considered a disability but I can’t remember if it’s considered a disability as a whole or if the case is severe
