I sometimes feel like someone is choking me. I can breath if I concentrate,but it is difficult to swallow. My last episode lasted 29 hours. it feels like I am wearing a shirt that is really tight around my neck but I am not.
This sounds like a respiratory problem but I am no doctor. I would advise that you get it checked, however.
Not all our problems are caused by MC, some have other causes. The nearest I can get to your experience is an asthma attack that was caused by my hay fever.
