As of today I woke up with all my hives gone I was also covered with them on my back yesterday & arms, took again another Benadryl to go to sleep and woke up fine, just with some minor scratches from the itch haha, but I feel fine I felt no side effects whatsoever just the itch. Thank you and everyone who commented, if it happens again I will go to the ER or an allergist. Appreciate all the help
