Two weeks ago I went to the ER for extreme pain in my jaw on the left side of my face. I was told that I had a TMJ disorder. Two days later I went to the ER again, because the left side of my face was totally swollen including the eye area. They did an X-ray and a CT scan to rule out a dental problem and I was diagnosed with a sinus infection. There was a large pocket of puss inside the sinus cavity in my cheek. I was given scripts for the Z-pack and a steroid.
Now, I have a small squishy bump on my gums on the left side of my face. It is far up on my gums - almost in the crease between my cheek and my gums. It only hurts when I bump it. And nothing comes out of it like puss.
My wisdom teeth were removed almost 12 years ago. The teeth below the bump both have had root canals and have crowns.
What is this bump?
