Infections of the throat
are quite likely to affect the ear
since there is a connection between the ear and
throat through the Eustachian tube. Common cold, flu, acute sinusitis, tonsillitis, ear infection, tooth infection all can cause sore throat and ear ache. Throat infections can be caused by bacteria like streptococcus or it could be a viral infection. Bacterial infections need antibiotics. Try warm saline garles.That may provide some relief.
