Hello! One week ago I went to an urgent care clinic with a swollen very painful place right below my ear. I was diagnosed with having an infected lymph node and impacted sinus cavity. I was put on Augmentin and an allergy med. 1 week later I have other symptoms...a cough, tightness and a little pain around my rib cage when I take a deep breath. (not in my lungs, I've had pneumonia so know what that feels like) I am getting chilled but don't seem to be running fever. I feel nauseous at times, light headed and no energy at all. And today a place (knot) has come up behind my other ear. Could this be just the infection working its way out? (I am a diabetic as well)
