what are the symptoms of Cricopharyngeal spasm?

Hi,

I thought I had the cricopharyngeal spasm in the past. If it *clicked* away from its regular place, I'd be able to massage it back into place. Last time this happened I was drinking something and something *snapped* and it no longer went back to its place. Then more symptoms started such as acid reflux, feeling crappy and tired all the time. I don't think those symptoms follow the C. spasm - but maybe they do in some cases. I'm headed for a barium swallow next week, so I'll soon know what's going on.
