Conversation: The conversation between human and AI assistant.
[|Human|] My husband has had an ongoing problem for longer than 4 years. Every 3-6 months his upper lip will swell like a balloon and he says he gets a "coppery taste" from it. I was thinking maybe he is allergic to parabens, sulfates, or some other chemical that is widely used in hygiene products. Is any of that a possibility? If not, what could the problem be?
[|AI|]  Hi dear, At the outset, all your husband complaints are suggestive of acquired angioedema, it usually caused by allergy. The skin of the face, normally around the mouth, and the mucosa of the mouth and/or throat, as well as the tongue, swell up over the period of minutes to hours. In my opinion, avoidance of allergen and use of antihistamines like Tab.cetirizine can prevent future attacks.please let me know if my advice helpful to you in any way. Best wishes.
