Thanks  <response>: Hi there. Your problem requires the attentions of a dermatologist on the ground. It could be any of the papulosquamous skin diseases aka psoriasis inverse or atomic dermatitis from your description. It may require a skin biopsy or path tests to confirm the treatment will be based on the yucca diagnosis. I dont know how much a liver tonic is going to help you but Good luck! Do add an antihistamine like fexofenadine 180 mg in the interim. Cheers!
