Cough since last 4 months . Whenever I move. Or speak (changing of voice pitch) . When I don't speak at all I feel I need to cough right away. When I just try to speak then cough comes again. I tried every other treatment from montair. To PPIs even nasal sprays and salines. It's really problematic. I don't understand why it's there. All investigations are normal this cough doesn't seems to go away. Hinders my concentration very easily. Pls help me
