I thought the itching may have been a symptom of this. They put me on Humira
the other symptoms went away but I still cannot tan without horrible itching. I have tried Benadryl, Atarax, Xyzal, Zyrtec and nothing helped. I have no physical signs like hives or rash. I have seen an allergist and have no allergies and my thyroid and blood tests were all fine.
