I am on day 6 of having a bad upper respiratory infection. Severe sore throat with coughing up mucous - discoloration yellow-green. Shortness of breath, it came on fast last Friday. Headache, sore throat, fever, chills, body aches and pains, cough and diarrhea. The mucous is so thick and it hurts so bad to cough it up. Hot liquids help, as well as cold medicine, but I can t sleep and it s uncomfortable laying down trying to catch my breath. I m also type 2 diabetes. At what point should i seak medical attention? I am pretty sure it is influenza with a complication of bronchitis.
