Hi , Thank you for sharing your father's story with the AD community! I'm so sorry to hear that his skin is not improving and causing him a lot of pain and discomfort. Also, I'm not sure if his doctor mentioned psoriasis as a possible diagnosis, but it seems that many of his symptoms overlap with psoriasis. If you're looking for more information, you can check out our sister site, PlaquePsoriasis.com. I reccomend him chatting with a dermatologist about treatment options to improve his health and get his life back on track. I'm sure this is a scary time for him, so if there's anything else we can help with, please let us know. Best, Sarah, AtopicDermatitis.net Team Member
