Hi,
Age and sex?
Chest xray?
Smoker?
On any medications?
Any other illness?
If the chest xray is clear and there is chronic cough and if you are not on any other medications, and also no improvement with steroid shots then the possibilities are -
1. Gastroesophageal reflux disease (GERD)
2. Post nasal drip
Upper Gi endoscopy and 24 hours pH monitoring may be done to see if you have GERD.
Sinus examination may be done to rule out postnasal drip.
