If its not reflux what makes my 9 DS bring sick up into mouth ?

[penguin70]

Bit of a story that may or may not b related. DS Started an awful hacking cough before Christmas and has had numerous doses of antibiotics, x rays and hospital appointments ending in a vague "virus" diagnosis. His cough is now much better though still there and he's constantly clearing his throat.

During this time DS came to me and said "ta dah!" and showed me a bunch of peas in his mouth - it was a good hour after tea time. I was a bit confused as to what was going on and he shrugged his shoulders and said food came into his mouth all the time. I don't know when this started, he was never a sicky baby but I've since discovered it happens 15 - 20 times a day if he doesn't have his medication about 4 if he does. Today he had a barium swallow; Dr didn't think he had reflux though had to do a more detailed exam of all the xrays before being definite.

He's not ill and not bothered by his symptoms but they bother me!! Any advice /thoughts please ?!
