After 6 years of suffering with hives and several doctors and prescriptions, currently on dupixent which is not helped as of yet, 8 weeks in, I have tried beta alanine. The one I bought never came with a scoop Soni guesstimated. That turned out to be a bad move. I definitely got the tingling, it was very annoying and uncomfortable, thank God it lasted only a hour or so. But.... omg for the first time in years I went in water and did not experience hives. I swam for 30 minutes and the sat in a hot tub. Normally I would be fully broke out. I only had a couple very faint spots on my legs. I am so grateful. I wish my dermatologist would have been able to diagnose this more carefully. I will contact him again to discuss. I will try this again today but at a more closely monitored dose. Definitely dont want that tingling effect again.
