Just another update:
I saw the doc today and he said everything looks very good. The wound is showing signs of healing well, and there is no evidence of infection. This will still be a long process, but we're off to a good start.
I am on track to return to work at the end of the month and today he also released me to drive again (freedom!).
I am most humbly grateful for all the prayers and support. I wouldn't feel this well today and wouldn't be healing well if it weren't for that. Thank you all very, very much!
