For anyone interested in reading about Laryngopharyngeal Reflux I found some very good web sites. One from New York Hospital-Cornell Medical Center
<http://www.nycornell.org/ent/Laryngopharyngeal.reflux.html>
and from Wake Forest University - Center for Voice Didsorders

GERD can cause problems in the throat area and is not always accompanied by heartburn.
Timidbird,
First of all what type of pill did swallow that got stuck? I personally can't rule out the fact that it could possibly still be there as bizarre as it seem. Strangers things have happened!
What type of medical doctor has your friend seen, besides a psychologist? Has he ever had an endoscopy or seen an ENT doctor? Has he ever had a CAT-SCAN or a MRI? Certainly these would show a yes or a no to what is going on. If it was me & I had not exhausted all of the above I would have an endoscopy done to see results then head over to the ENT.
I hope I have helped a little. Post a comment on what unfolds.
