thank you so much for the information; I am deadly allergic to penicillin.
Hi, the condition strongly suggests angioedema which is due to hypersensitivity reaction (type 1). One thing is certain that alcohol is a allergen to you and subsequent exposure to it can cause complications. Hence, you need to quit the alcohol completely. You need to keep always antihistaminic with you. You also need to rule out other allergens which you are sensitive to. Drugs like amoxicillin, certain painkillers, certain garments, environmental allergen and certain food (fish, mushroom, peanuts, soy etc) can also cause such reaction.
You need to keep track of things (maintain a diary) you were exposed to such as food, cloths, drugs etc. and you should avoid further exposure.
This is a emergency condition because there will be associated laryngeal edema leading to breathing problems. Drugs like Adrenaline, anti-histaminics and corticosteroids are the standard mode of treatment which should be taken after consultation from physician or hospital. Take care and regards.
