Hello Marsha, Some of the symptoms you describe are similar to those caused by diminished thyroid output. Do you know if your mother has been tested regularly for thyroid hormone levels? Thyroid problems are quite common after radiation and are common amongst older people.

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.
