What are the worst injuries you have sustained doing the simplest, most mundane tasks that should not have caused any injuries?

I was sleeping at a hotel and was awoken by the worst leg cramp I've ever experienced. I tried to fight through the pain and stretch the muscle for what felt like an eternity. With the pain still overwhelming me, I desperately resorted to rolling out of the bed to put some weight on the leg in hopes that it would help. Unfortunately the pain was so severe that I fainted and rag-dolled onto the coarse hotel carpet. I woke up moments later to a heavy burning sensation on my cheek and forehead. Once I gathered myself, I hobbled over to the bathroom mirror to inspect my face. What I saw was 2 large bloody patches of rug burn that had sanded off layers of skin.

I still have 2 lightly colored scars from the incident.
