Hello! I've been getting hives and red swollen spots on my wrists, hands, elbows, and knees after I started using whey protein powder. I do wanna keep drinking protein powder but I'm tired of having the itching welts and hives. I eat a Benadryl every day

Urticaria. There's a lot of different formulations of protein powder out there. You should look at the ingredients and try to use the one with least preservatives. Hives on just wrists, elbows hands and knees sounds a bit odd..but anything can happen with the human body. Benadryl (diphenhydramine) will only mask symptoms and make you drowsy. Ask your friends if they are having any issues with their supplements as well.
