This morning I woke up with a small kind of like "Clear blob" with normal red gum stuff around it. I'm not sure if this is an infection or a cyst. I was just a spontaneous thing I woke up with and wasn't poked or burnt as far as I remember. I DID try new foods like MooShoo (Not sure how to spell) Chicken with some dressing stuff and some Indian Naan bread or something like that (Not good with these ethnical food words...) Also I wear a retainer at night but I've never had this effect and don't think it caused the bump. Its not a kankersore (Spelt wrong I think, sorry) I know because the school nurse said they were usully more white. I tried rinsing with a solution of hydrogen peroxide and tap water (50/50 of both) but I didn't experience much burning sensation except for on top of my tongue where the problem wasn't. So what should I do now? I'm not sure what it is. It's a little sore but doesn't bother me unless I am poking it. What should I do? What is this? My blood pressure is normal.
