I tried taking Benadryl, but it did not help at all. I had hives basically from my bra line down with some in my groin area and a bit on my arms and neck. It all went away on its own, but it took 2-3 weeks. The itchiness was miserable, but the cortisone cream helped.

You should call the hospital and ask them about leaving. I could not leave on my own. I had to uber my son to the hospital to go home.
For the liquid diet I was told broth clear like fluids only w/ 1 small daily meal.
Lastly I turned out to be highly allergic. If possible I recommend asking what they use to clean and patch you up and see if you can get an allergy test prior.
