Do people who stutter sometimes feel they they can’t breath or literally can’t for a short moment?

Do people who stutter sometimes feel they they can’t breath or literally can’t for a short moment? Please answer this this is important because I’m doing a study: If stutterers feel physical difficulties because of it. And in my experience I do. When I’m having one bad block, I’m literally suffocating because it likes it locks my airways up and with my asthma it makes it a bit worse. And when I’m having a bad stutter moment, I feel air get blocked in my nostrils, and I’m constantly out of breath when talking because of it.
