It Feels As If I Have A Lump In My

It feels as if I have a lump in my lower cheekbone. It radiates pain to my ear. I was thinking it was a toothache until she told me today she sees nothing different front last xray. It hurts when u push on it. My face looks alittle swollen. Have a history of basil cancer taken out of nose. What could this be. The dentist put me back on cephlax for 7 more days!
