Scraping With A Sharp Exhalation And Laughter

Hello! I have a strange problem. When I was younger, somewhere around 13, I got sick more often and coughed normally. But around this age, somewhere I had a problem - as I coughed sharper and harder, there was a scraping in the trachea, ie high almost below the larynx. (The place varies to high between the breasts) This scraping over the years began to be felt even with a normal cough. Even with a sharp exhalation, for example, once my volume was measured with an instrument or I don't remember exactly what my lungs were, but I had to exhale sharply to the end and when I exhaled it scratched me again. Besides, when I laugh a lot, the laughter itself is generally a kind of sharp exhalation, but you can hear scraping again and it's very nasty. It sounds very nasty and I'm ashamed to laugh like people. I don't know what it is, but someone had told me it was an allergy. Allergy from what And is this even true ...
