Hello, I regularly experience what feels like an internal itching in the centre of my back, which is accompanied by wheezing. I find this is brought on after I have been laughing, which is rather worrying. My wheeziness and itching back can also be brought on after I have been outside, and the air is damp after it has been raining outside. I did contract a rather nasty chest infection about 15 years ago, and my symptoms have remained.
