What should I avoid if I have strep throat and fever?

Hi Thanu There is always a reason for your body to develop a fever. The important thing is to find out what is the cause of the fever and treat the underlying cause, rather than just the fever itself. A very high fever on its own can also cause other problems like brain damage (especially in very young children). That is why I recommend seeing a doctor and let the doctor examine you to find out what is the reason you are having the fever, and treat you accordingly. He may even have to run some blood tests if he suspects diseases like Dengue or Zika.

Yes, it is possible for sinusitis or a middle ear infection to cause pain in the upper back teeth. This is a phenomenon known as referred pain. Referred pain occurs when you perceive pain coming from an area that is not diseased. This is due to the sensitization of adjacent nerves. Neurochemical changes that occur as a result of a disease process in the area supplied by one nerve (the sinus) can sensitize another nerve running close by as the nerve branches converge in the brain.
