I haven’t been diagnosed yet. I had Hodgkin’s lymphoma in 2022 and had a pet scan two weeks ago which showed a glow up in my groin I’m having a biopsy next week to see if it’s come back but have come out in this rash. I’ve been to the doctors about it and they sent pictures off to a dermatologist which has said it’s urticaria.

Yes. No dermatologist ever found a cause. After several years I gave up. A member of our local lymphoma community suggested kelp tablets and it helped me.

If it’s cutaneous t-cell lymphoma it initially gave me very, very dry skin along with serious intense itching. Then in various locations red patches that look like and turned into blisters and itched like Ahhhhh ! Check with a good dermatologist.
