[|Human|] My wife has severe itching over most of her body. It is worse on her back, across her chest, on both arms and behind her knees. She has no allergies we are aware of. Has been to doctor 4 times over last month. One biopsy was inconclusive and we are waiting on results from 2nd biopsy. She gets about 3 hours sleep a day and heat makes it worse. Please help...
[|AI|]  Hello. Thank you for asking at Chat Doctor. I reviewed your wives history and one most important think I would like to ask you is whether she has only itching or itching with skin rash? If she has itching with skin rash, I will first think of chronic urticaria, and she will require long term regular montelukast & levocetirizine. However, as you haven't mentioned skin rash, I assume she has only itching and therefore am I elaborating it in detail. There are many causes of itching like diabetes, thyroid problems, Chat Doctor.
