Ocean-induced hives?? Please help
I've been swimming at the beach frequently since I was little, without any problems, but just a few years ago I noticed that I flare up with itchy, red hives all over my body every time I swim in the ocean.
At first, I thought it was cold-induced because I also tend to get these hives in cold air, but I recently noticed that the hives are now raised and much larger than before, specifically from swimming in the ocean. I also get little raised hives from sweating, so maybe it has something to do with the water contact itself?? I feel totally helpless. Taking antihistamines like benadryl has never helped with this. I saw a doctor about it once, and they attempted an allergy test on my skin, to which I reacted with hives to everything (including the negative control) and was told I had dermographism.
Maybe it's true that there is no treatment, but I was hoping somebody on here could offer some advice or at least a suggestion for further research, because I'm really sick of feeling itchy, uncomfortable, and insecure trying to enjoy the beach. Maybe a solution stronger than benadryl that I don't know about yet? Anything helps!! Thank you so much!
