is a sinus infection, that causes green phlegm from nose and lungs, a sign of ARS symptoms? exposure was 15 seconds of unprotected oral sex given to me from a female. i am a male. these symptoms developed 2 weeks after exposure. 2 weeks post exposure i had a fever for one night and massive pressure on right side of face. assumed it was sinus infection. today, still coughing up light green phlegm in the mornings 4 weeks post exposure. Other than that. i feel normal. thanks.
