Flu Season: In most cased pink eye is found during or after a viral illness. So, yes, these are often related and happen at the same time.

Relationship: The same bug that is causing your pink eye can also cause your sore throat. The source of both infections can be your nose.

Yes: You have a viral syndrome (viral infection). Causing swollen throat and conjunctivitis, pink eye. Hydrate with fluids, decongestants, salt water gargles, rest. See your pcp if conditions worsen or you get a productive cough or sinus problems.

I sure do: The most common cause of "pink eye" is adenovirus. This can also cause a sore throat.
