I saw snowy trees and fields while walking past the park. More later.
Update, a few hours later: I gained a clearer understanding why it is they seem to be procrastinating on doing further surgical work. The issue is that to dig down deeper in that area puts my right sublingual nerve at risk. This is a really big issue, because I lost most of the functionality of my left sublingual nerve during the cancer surgery. So my tongue has been operating all this time on the right nerve only. That's one thing the doctors mean when they say my tongue is asymmetric. So the one thing they really don't want to do is mess around with the right one. So anyway. They looked there, they said that some bone was showing (which somehow implies it's necrotic?), but they decided to continue to "wait and see." I'll go back next month.
