Your sore throat may be caused by a virus, a bacterial infection, a yeast infection, or irritants (such as refluxed stomach acid). Most of the time, a sore throat does not require a doctor's evaluation. If you have symptoms that come from a common cold, then you probably do not need to visit your doctor unless you would like to receive your own doctor's advice about over-the-counter treatment options.
Do you also have a runny nose, stuffy nose, or sneezing?
