This has happened to me before. One night the cupbored with all the glasses in fell down and all the glasses smashed in the kitchen. I woke up, and sleepwalked downstairs and into the kitchen. I got a sandwitch from the fridge and went back up to bed. The following morning there was a half eaten sandwitch and a pool of blood all in the bed and up the stairs and evrywere. I couldn't feel my feet. Straight away i paniced and rushed to the doctors, which is just up the street. I was reffered to A&E. They put bandiges on my feet and i was ok. Apart from i couldn't walk for 6 monts after.
I don't know how they removed the glass shards from my feet, i'm just thankfull i can walk.
