Hi Netsy

i think the best thing to do for now is hope that this is no more than radiation damage to his trigeminal nerve,fibrosis possibly from the radiotherapyand other general gifts from treatment.All of the above could account from most of his symptoms.It is such a short time span from completion of his radiotherapy to developing these problems .How did his scans look at diagnosis and what did they see during surgery?I know from personal experience that recurrance can hit hard and fast,but please try not to think the worst straight away.
