Sore throat: Viral illnesses can cause tonsillitis and ulcers in the back of throat. Gonorrhea which is transmitted sexually can cause pharyno-tonsillitis but most infections are asymptomatic.

Seasonal flu : Seasonal flu is very common viral infection. Usually the condition resolves on its own with home care. Drink water and get a good rest. If concerned, see your pcp.
