I've had a fever, dry cough and a headache for 4 days now. I also feel pain in my right lung when I take a deep breath. I'm diagnosed with asthma.?

Fever cough. Follow up with doctor/urgent care. may need antibiotics could be mycoplasma for which zithromax helps. The pain on deep breathing is likely pleurisy -inflammation of membrane around lungs(rarely PE doubt it, unless you smoke are on BCP and have family history) But f/u with doctor urgent care today.
