Thank you everyone for your responses. Leon already seems a little bit better. He has a little more energy, seems a little stronger, still no taste. He had his first doctor's appointment with the RO on Friday - 1 week out from his last rad. The doctor scoped him and said everything looked smooth and vocal chords and muscles were working normally. He doesn't have to see him again until April 7th. The RO said at that time he will schedule a CT and PET Scan. Does that seem a little soon for the scans? Again, thank you for the help.
