I was itching like crazy, had the hives too. Doc thought it was one of my meds. The hot water made it much worse, but cool water was okay. I still have a huge amount of bruises on my thighs from itching. The doc gave me prednisone for the hives, but the itching persisted after.

Doctor Mom to the rescue! My mom said that her doc suggested Zyrtec, so I tried it and it's been great. Maybe I'm just allergic to something outside. Maybe it's the heat, maybe some stupid exacerbation, I don't know. But apparently the Zyrtec is specifically good for itchy skin.

It's not cheap. She was able to find it at Sam's Club for $15ish for like 300 pills, I could only find 14 pills at Target (their brand) for like $6. We don't have a Sam's or Costco here.
