I had a severe sinus infection and it goes in and out... I had like a ball on thge right side of my face lower bottom tooth. It hurts. Wat is this?

Dental abscess. If the swelling is on one of the lower teeth (along the lower jaw line) you don't have a sinus infection, but you are probably developing a dental abscess. Either way you will need antibiotics. If it is dental in origin, the offending tooth will have to be pulled. Get seen quickly to prevent a severe abscess which may require surgery to drain. See a doctor or dentist asap.
