Wishing you a smooth recovery.
I had the main salivary gland in right side of my neck removed a few years ago because a salivary stone had formed deep inside it.
Was back running a custom rough in 2 days later.
Doc never mentioned future kidney stones.
Now I get cramps in my neck when grunting in an attic trying to fit in a small space and force a paddle bit through a top plate. It also happens when opening wide for the dentist or trying to eat an over sized sandwich or hot dog. Only way to relax it is too look straight up with my mouth wide open and roll my head around till it pops back in.
This is never much fun in an attic with no headroom however it produces interesting results at a racetrack where people around me are wondering what the guy with the mustard on his shirt is looking at up there.
