I think I Have been doing too much

*looks at the heel of left foot*

Yes, my back is a bit twingey, but that's not the problem. Been doing a lot of hauling, weeding , pruning, raking, chucking, sorting, and lots of walking. My left leg is getting tired, but I don't feel it. What happens is my left heel strikes the floor too hard, causing cracks, both across and under the heel, and it doesn't matter if I wear shoes or not.

They're not quite bleeding... yet. *wince*
