After four months, today the cast came OFF! Woohoo! Woohoo!! WOOHOO!!! It was replaced with a splint that I wear till I go back in six weeks, but the splint can be removed several times a day for light exercise, like TYPING! (Indeed, doctor's orders!) And no more plastic bags taped to arm while showering! Oh Happy Day!
It's not done healing, but it's 'much improved.' It's very weak, so lots of progress to make. Still must use the bone stimulator daily, and not over tax it or strain it, and must massage the scar tissue (ouch), but very happy and thankful am I.
