Hi there i have woken up with a really swollen top lip could this be allergy related? had a sore to start with on the inside of my top lip yesterday but this morning it has magnified to my whole lip.

Swollen lip: You mentioned that you had a"sore" on the INSIDE- was it a blister( full of clear fluid) or a lesion ( painful red ringlike )? Allergic reactions that manifest in the lips are potentially dangerous- and should be examined immediately, especially if you are feeling any breathing changes or the swelling continues. Contact reactions are usually not painful but do not start with a "sore". Take benadr
