My spouse has had a dry cough for the past two months. It's not constant or really severe, but it's been lingering for a while now. It all started with a fever and wet cough for two days, but now it's just a dry cough. He's been on medication for a week, and although its improved a bit, it hasn't completely gone away. Oddly enough, he sometimes starts coughing after drinking water. I'm really hoping to find a permanent solution to this. Could you help us figure out what might be going on?

Ecg,sputum for AFB ,microscopy and x-ray chest pa view is advised to the patient.
