No, I was banded in Decemeber 2010 and yes, I do remember a blister from the tube down my throat. But this is different. Also, when I went to my support group meeting at the doctor office, a lady mentioned her gums were peeling. Every since I heard that, now im getting something weird in my mouth. It must have to do with lack of something my body is not receiving. ughhh so frustrating! maybe I should go to the dentist!
