My question is, what would cause itching of the abdomen, chest, legs, back when it is not caused by allergies or weather. I have been itching all over for about 4 months now. There is no notable rash and I have eliminated everything but breathing to ensure it is not allergy. My doctor several months ago thought it might be allergies and I eliminated everything changed soaps etc. but to no avail of relief. I have tried body lotions, antifungal lotions, calamine lotion, you name it and not relief. Any suggestions?
