I had a sore throat for few days but today after i finished brushing my teeth i sneezed then had this sharp pain in my throat. is very painful even to swallow saliva.

Dr. can check it out: Throat pain can be from strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), sinusitis, or from some other cause such as allergies or irritants. Usually a person sees a doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to check for strep throat). Some throat lozenges can temporarily lessen the throat pain.
