I'm suffering for the last few months with on-off symptoms of feeling like i almost have swallowed a cow (before you ask, no, i've not swallowed a cow).
It's like something is 'stuck' by my adams apple and a sense of feeling sick. It comes and goes without any real logic i can pinpoint. Sometimes like today when it's quite bad i get a shortness of breath during exercise and a higher heart rate than usual to maintain exercise rate/speed/etc.
apart from the obvious answer of bad aids... any other ideas ?
