Breathing problems: If you are experiencing cough associated with significant fever, you may very well have pneumonia, and that will require an antibiotic. Most lung inflammations are associated with fatigue, but this is a nonspecific symptom. Other potential causes include a blot clot in the lung, tumor, and other inflammatory conditions of the lung. So, yes, it could be something bad. Best to have it checked out.
