Hi Shannon,
Thank you. Nope, no mass--just some irritation. But, that was after the tonsillectomy. He chronically clears his throat and has done so for years--which was his only symptom. Actually, at one point I used echolocation to determine his position in the grocery store. Absolutely true. (Any other resemblance between me and bats is strickly coincidental--despite his opinions to the contrary.)

He's taking Prevacid which seems to have calmed his reflux and he doesn't make that noise very much anymore. Thank. Good. Ness. He seems to have better luck when he avoids eating late in the evening...and remembers to TAKE the Prevacid.
I hope that you get an "all clear" on your test results.
Congratulations to your dad and mom for being survivors!
