Hi, I have what seems to be a kinda flat piece of tissue on the inside of my cheek way back on the left side kinda close to my wisdom tooth and I have had it for maybe close to two months, and a couple weeks ago there was this sesame seed sized thing with a little bit of blood in it, almost like a mini blood blister I guess. It dosen't really hurt but it get's a little agitated. A little before I noticed the tissue I had horrible jaw pain and swelling in the area where the tissue is now and I could barely open my mouth. My jaw is a little tender sometimes but dosen't really hurt now. I have a doctor's appointment for this on Tuesday but I just wanted some opinions. Oh, and I am a 20 year old (21 July 2nd) female and I don't smoke or drink. Thanks ahead of time.
