I have a cold or sinus infection or bronchitis. I can t get rid of my fever, i ve had it for 10 days running from 99.4 to 101.5. Coughing is causing loss of sleep. Mucus has become more clear, but after having no fever yesterday, it is back tonight, 99.5. I m discouraged with having to rest instead of being active. I take no medications because of so many allergies. Should I just hang in or should I be concerned? Symptoms are not as bad as the first week.
