Get seen...: If your oxygen is low this is most likely something more complicated than an upper respiratory tract infection. It could be a pneumonia but no way to tell for sure until you see a doctor. I would suggest to go to the ED for immediate evaluation. ...Read more

Wheezing/Cough: Feeling weak and tired with coughing up green mucus is concerning for infection, somewhere. Wheezing would suggest the lungs. Could be asthma exacerbation, bronchitis. Could also be a sinus infection since the nose/sinuses are "stuffed up." most often for infections of the sinuses or the lungs or airway, you might need antibiotics. Try a nurse practitioner, they can diagnose &treat for less $. ...Read more

Cough: Yes you could but could also be a viral illness. Would stay hydrated and take tylenol (acetaminophen) or Ibuprofen for aches. If this is viral, it should be getting better in a 3-5 day period. If symptoms progress to include fever unresponsive to otc medications/ nausea-vomiting-diarrhea causing dehydration then you need to see a physician. ...Read more
