My mother have left lung cystic fibrosis since 30 years & 4 months back she was treated with bronchial artery embolization for bloody sputum. Now she has mild throat pain since 20 days only in drinking water and swallowing saliva, but not in eating anything. She was diagnosed with granular pharyngitis, doctor gives different antibiotics moxclav / ceftum. But there is no change in her mild throat pain since 20 days. Ent Dr. Told there is no sign of cancer, but there are granules all over in neck. I want to know since already 20 days had passed, so how long will it take to recover from this throat pain.
