Lately, I've been secretly feeling itchy and developing hives.

Recently, I have been experiencing frequent itching on my body, so I thought it might be because I haven't been washing properly, and I went to a public bathhouse. Even after that, my body itched, and when I looked at it, I saw hives. So I applied ointment that I have at home. I thought it would get better, but the itching still persisted, and I found it strange. I searched the internet to see if it might be shingles, but it doesn't seem to be shingles. That eased my mind a bit, but I still feel itchy and it's strange.
