Hope you'll heal that up soon, too. And whatever comes next, though hopefully it won't, but that's unlikely. Vitamin D insufficiency is quite common. I learned that even I have it, living in Ecuador. Since I'm taking a supplement, I have a lot more energy and am generally in better shape. Now, I could change my diet again, but to be honest, I'm too lazy right now. Other things are more important, so supplements it is.
