There's a scar from a compression cut/gash to the bone in the front of my shin that aches when the weather is about to change. I got it the last time I made the hike to the 'Subway' many years back. I had to use TP and a shoelace to help bind it until I'd hiked out. There was blood everywhere! It looked really bad, mostly because it was. The doctor commended me on my ingenious field triage techniques and then put about 40 stitches into me. I knew one day I would have to return.
