Thanks all for the thoughts and prayers.
Incredibly though, it has not been sore, little pain but had much worse. The doc said it needs to be taken care of though or would lead to rotator cuff issues, or other bad things that would be much more painful.
Surgery went well, now pretty much right hand immobilized for two weeks. Then go back to check healing process of tendon to bone. Hopefully get OK to proceed to physical therapy.
