Hi Kelley
A tight throat is often caused by anxiety - even the Greeks knew this and called it Globus Hystericus, although there's not much hysterical about it if you ask me.
But of course, as with all these things, if you are seriously worried you should see your doctor.
One check is to relax deeply for half an hour to an hour (using say
hypnosis, and see how your symptoms are then.
All the best
