Coach,
Although we have never met, I understand what you are going through. I underwent a parotidectomy last March, after diagnosis the week of the league tourney and surgery the week after State. The stress on our family during my son Joshs state run was difficult. Support from Wrestling parents that we have known since Kids Wrestling was a great help in keeping my sanity.
In my case the tumor was benign. The facial paralysis was frightening at first but has completely reversed and feeling has returned to about 95% of the affected area. From a personal experience stand point, my recovery time was about 4 weeks. The pain was much better by day 3 and I was able to eat normally by day 5 following the surgery. Follow the doctors orders and don't rush back. Although this is a trying time I am sure you know, as a wrestling coach, a little about mental toughness! Stay strong, lean on friends and family and know the prayers of the wrestling community are with you.
Good Luck and God Bless
