I hope i can get some help here. I have been to the doctor and no prognosis. I have had sinus, and chest congestion for more than 2 weeks now, with a low energy level. I don't think it is allergies, no sneezing, or itchy/ red eyes. The doctor gave me a steroid shot and put me on an anti-biotic, and Phlemex to break up the mucus, no real relief. I was taking Tylenol cold with no relief. What could cause all this? I have been unsuccessful with any searches to what i am experiencing.
