If I get sick, when do I need to see a doctor?

Please see question, “If I get sick, what do I do?” above. Symptoms that your doctor will worry about (and want you to call them for) include any shortness of breath or difficulty breathing, any wheezing, any chest pain, or any blood in your sputum. For most, assuming you feel otherwise ok, even a high fever is to be simply treated at home with ibuprofen (Advil or Motrin) and acetaminophen (Tylenol). Monitor your urine output for healthy and relatively frequent light yellow urine, if you have a home oxygen saturation monitor (aka pulse oximeter),  you can monitor your oxygen saturation to be sure it is over 92%, and that your heart rate is under 110, otherwise CALL YOUR DOCTOR, who may well recommend a trip to the Emergency Department for evaluation and treatment which may include oxygen, IV fluids, X-Rays, and urgent supportive care.
