Dear Opal,
I went through the exact same issue whilst on W&W specialist advised me that they had seen it in a few CLL patients,I used to get itchy welts all over the body and I would h ave to rub up against the door jam to get some relief.I had 12 biopsies taken of the welts when they were active but alas nothing.I eliminated foods etc one by one and again no results.I was advised to turn down the temperature on the shower and avoid wearing clothes that are too tight and will cause the body to heat up,I did this and it helped but didn’t go away,only one thing left to do,I was using a topical steroid(not strong)for a mild case of psoriasis, I stopped using it and low and behold it all went away.
I don’t want to steal anybodys thunder but one of the previous replies touched on this .I hope this helps as I know ,that itching ,drives you crazy
It has never returned.
