What is causing this? And is there a way to stop it without having to take showers basically 5 times a day because it certainly doesn't seem normal and it didn't used to happen.
Maybe try searching for cholinergic urticaria to see if the red marks look similar? (They're basically hives.) I've known two people who developed CU later in life. Antihistamines helped for one of them. The other is still just showering all the time.
I guess it looks somewhat like this, certainly not that bad though.
