Now that this has been brought up, I have experienced this, too.
I have difficulty breathing when my mucles in my upper back and neck/chest area are in so much spasm, it feels like I've got a necktie on and someone is constricting my chest. Also, I get esophageal spasms when it's really bad, causing the tight necktie feeling, and swallowing/ breathing problems. It's lovely, let me tell you.
