I've been experiencing this strange unstoppable cough which often gets so intense that it leads to fainting.The cough starts with a bit itchy feeling in the throat.
This started 2 years back in 2017,i had consulted doctors (both ENT & Pulmonologist) they tested my throat and had PFT done and found nothing! He gave some medicine which probably cured it but i personally believe it cured by itself.Nothing happened after that!
Now few days back,the cough started again! This happens especially when I'm in a stressful and in anxious state.
What could be the reason for this and what is the cure?
