My husband has a bad cough. He has had it for about 6 weeks. He has been to the MD 3 times. His blood test indicates it is not Valley Fever. His chest X-ray indicates there is no problem with his lungs. What could it be? His MD has no ideas and does not know what or if he needs meds.
Hi, Thanks for asking. I understand your concern.  Persistent chronic cough can be due to- - Chat Doctor.
