Yesterday I was on a walk and I started to get what I thought what looked like a mosquito bite, and then a reaction to it, which also looked like smaller bites around my elbow. I ignored it and it later went away, thinking it was only a bug bite. A few hours later the same process happened on my other elbow but much worse, then started to go back to the original elbow. The skin was warm to the touch and red. I put some calamine lotion and took a benadryl and went to bed. It went away but returned when I woke up. 24 hours later I still have isolated hives that come and go on spots around my elbow and arm almost constantly since yesterday. Nothing too severe yet. I have no allergies, I don't get poison, and I didn't come in contact with any chemicals. I did have a stomach bug 2 days before, but I am not sure if that has anything to do with it. Did anyone have this happen. I hope tomorrow its gone and never returns. Any home remedies? Thanks!
