question: Hi :) I'm 30 and I brush and floss daily. My teeth and gums look good. A few weeks ago,  I felt a vein type thing on the inside of my left cheek and it felt like my cheek was swelling and then going down.  It didnt look swollen. My throat hurt on and off as well as my ear. A few days later I felt pressure in my mouth and a tooth which looks normal. It's not hot cold sensitive nor does it hurt to eat. It does feel like food keeps getting caught under the tooth. I went to the doctor last night and he mentioned it could be sinuses and the vein thing on my cheek is my teeth line. What do you suggest?
