What could be the cause of my chronic cough? (it is not asthma, gerd, post nasal drip or any of the other typical problems)
Many diseases could cause those symptoms including viral, bacterial and fungal infections, sarcoidosis, wegener's granulomatosis, malignancy, rheumatoid arthritis, lupus, churg-strauss vasculitis, etc.
You should see your doctor to begin a work up.
