Hi. I went to a clinic with flu like symptoms, flu tested negative. Doctor went back and forth between sinusitis and flu and decided flu. Gave tamiflu with little improvement. Issues changed. No drainage, sore throat, congestion, body aches or pressure. Now nausea and extreme fatigue. Went back weeks later. At this point had cough, sinus issues again, burning chest upon cough, green mucus. Was given amoxicillin/augmentin and cortisone shot. Almost done with meds. Went from burning aching chest pain during cough, to during breath to 24/7 and now its in my collar bone area too with upper back pain. Help!
