Suggest Treatment For Nausea, Post Nasal Drip And Ear Fullness

Question: I thought that I had a taco chip stuck in roof of mouth yesterday after dinner. I found a hard, what looks like a pimple, on the roof of my mouth. Just right of the center of roof of mouth. Today when I swallow I still feel, and see, the bump but it feels like my roof of my mouth is a little swollen now, the pimple is still white and hard. My ears feel full and I have nausea. Two nights ago, I became very nauseous and threw up (before I found the bump). Can the bump be from an infection, or a chip stuck up there? How do you know it's not cancer? My ears also feel full and burning. Do I see a primary care physician, ENT or my Peridontist? Of note, last week I had a deep cleaning around some of my teeth to the point were I was bleeding as she was digging so far into my gums. She thought there was something stuck up in the gums so keep digging. Could this have caused an infection? My tonque is also white and roof has some areas of dark red, vein and yellow/whitish areas today. I don't think so. I have had some chills and a little achey. Ear fullness. Extreme nausea off and on and some drainage down back of throat.

Thank you. I've uploaded 3 pictures. No popping, just full feeling. Very nauseous and back of throat feels more swollen today than yesterday and like drainage or thick mucus.

Im sorry, I cant keep paying as they have been uploaded a few times. A primary care doctor was able to view them so Im not sure why you havent been able to yet. Maybe he was accessing at the same time. ?

Thank you. How do i get the precriptions? Also, do you think these correspond to another symptom i have which is scalp soreness? It feels like Ive had a pony tail up for weeks? It looks like the pimple on my roof is gone today but my roof of mouth is a little yellowish. Also, extreme nausea.
