I am 26 years old. I have smoked lightly, less than a pack a day, since I was 20years old. I have barely ever drank but maybe twice a year. Question is, right now im 23 weeks pregnant and two months ago in mid day began having jaw and ear pain on my right side. Could this be oral cancer? I also have swollen lymph nodes, one behind my ear and jaw on the same side as the pain. I have a history of allergies, sinus problems, and ear infections. I ve been checked three times for this within the last two months. Doctors say no ear infection, but say it could be tmj. I also had my top wisdom teeth come in earlier in pregnancy, but no bottom ones yet. Im worrying what it is. Im going to a dentist in a few days to get checked. Just wondering your opinion. Thank you.
