I have a hard lump on my hard palate I

Patient: I have a hard lump on my hard palate. I don’t know how long ive had it, I noticed it while looking at a cavity. Im afraid this may be something serious such as cancer. I also have a much smaller lump on my inner bottom jaw. Ive had it for a long time. It has not grown. Neither of these lumps hurt but I am still worried.I also have TMJ, I’m not sure if these lumps can be a symptom of TMJ?Additional information: I do not smoke or drink. Im 18. I had an ear infection a few months ago that I did not finish antibiotics for. I currently am having sinus issues.

Symptoms: Headache, sinus pain and congestion.
