Sammie, If he is still taking pain meds they will cause more sleepiness. The stress of it all can also make a person tired. Depression which is common post treatment is the one thing to keep an eye out for. If he is up to it get him out for walks.

You haven't said that he was treated at a comprehensive cancer center or major hospital. It is worth considering a second opinion about the radiation. This cancer is noted for coming back due to microscopic cancer cells that surgery alone could not reach. I am not trying to second guess his doctor, rather for you to be certain. Radiation is no fun and if you can avoid it that is great. On the other hand you do not want this coming back!

Mark, 21 Year survivor, SCC right tonsil, 3 nodes positive, one with extra-capsular spread. I never asked what stage (would have scared me anyway) Right side tonsillectomy, radical neck dissection right side, maximum radiation to both sides, no chemo, no PEG, age 40 when diagnosed.
