What about an infection that seems to be only in the lungs that has lasted a month? I’m coughing up yellow, bad tasting stuff over a month. But I’m scared the antibiotics will make it worse . My sinuses seem ok . But I feel gross stuff draining from my sinuses down the back of my throat. But when I blow my nose, nothing comes out or it’s clear .
