I have got it....I think. 3 years ago I had a strange crackling and couldn't breathe. I thought I was dying. I managed to calm down and breathe okay but still went to the doctors.
The difference was that I had returned from a long flight the night before and arrived home to a house full of bird feathers and bird poop. It had been trapped in my house while I was away.
I have had several other instances of the crackly breathing but always assumed it was a seasonal allergy. I have been away on a Greek island with high winds and I couldn't breathe most of the time, very short of breath.
Im now beginning to think the thing 3 years ago was a triggered attack of something related to a bird allergy and so was the effect of something in the winds at Mykonos/bird feathers etc in the air.
Can Asthma be triggered by birds?
