so i had surgery done yesterday, and while i was under anesthesia, the doctors apperantly put a tube in my mouth and taped it to my bottom lip to keep my flow of oxygen. when i woke up, the tube was already removed but the area where the tube was was swollen.  it was just puffy and red at the time. but when i woke up today, it looked more like a blister or cold core or something..should i be worried..?
