Doc tested me neg for strep Tuesday. Looks like strep, & pimple-like in back of throat. Lost my voice. Today, woke up w/red eye. Why? What is it?

Probably viral. This sounds like adenovirus. Adenovirus will give you a sore throat and also cause conjunctivitis. Drink lots of fluids, should get better soon. Also laryngitis (losing voice) goes along with viral illness.
