My upper lip is numb on a small area after the endoscopy, I woke up with swelling pain and numbness. I saw a small cut on my upper lip (inside) I saw my family doctor the next day, was told to ice it and keep an eye on it. This really bothers me.This sometimes affects my speech, eating and drinking. When I eat it causes my lip to have more numbness. I have talked to the endoscopy people and they had the gastroenologist call me. I was told it may be from the mouth guard they use. I was told to see my dentist if I’m concerned that I should get feeling back. I had this done January 25, 2018.
