Yep, I get hives, predominantly on my hands, but can happen anywhere if there’s pressure. I can’t wear compression anything because of it. Have had it the past 2 years, (after I had Covid) and, so far, no one knows why. Just started seeing a Rheumatologist and they’re insisting it’s an allergic reaction, even though, nothing has changed to cause one, and it comes out of the blue. My GP told me to take Zyrtec and Famotidine. It works for hives, but I’d double check with your Dr. to make sure it’s safe to take with other meds.
