[|Human|] I am 79 years old. I have what feels like a swollen lip inside my mouth.  It is not sore. When I rub my tounge over the area it feels rough like rigdes (not bumps) It seems to  be more noticeable with some foods, such as peanuts and lemonade.  This has been noticeable for more than a year.
[|AI|]  Hi there!seems to me thatching you for your question in ChatDoctor.is AIT seems to me that you might have an allergy to certain foods like peanuts and lemonade. You also might have had these allergies since sometime, but might have noticed it now. If possible, do try to undergo what is called the allergy test, wherein they will diagnose the allergen (food or chemical) to which you are allergic to. That can give you a general idea as to what foods/ items need to be avoided. For an acute episode of allergy, you can take an antihistamine, like Cetirizine 5 mg, which should stop the swelling in your lips. Hope this helps. Cheers!
