I suggest that you see a dentist.
For the past two days my tooth is hurting that affecting my right side of the ear and i have the worst headace ever?
I believe you have a tooth infection. You I'll absolutely need to see a dentist asap before it spreads. Hope you feel better.
Could be your sinuses especially this time of year. However, it may be an abscessed tooth in which case it's very important to see your dentist to get some antibiotics.
Could be sinus, but I'd try to rule out the tooth.
