Update saw my Hematologist decided I was not allergic to Gammagard. So I received my IVIG infusion. The dermatologist gave me a steroid cream to use twice a day for one week. I had an appointment with my Rheumatologist yesterday and he said the biopsy results show thickened skin as a result of chronic itching and rubbing. Back to square one. Not sure why I had the itching. Haven't change medication and no new foods.
