My foot
My right foot gave me tremendous trouble in high school. Part of it was from how weak my bones were in the first place, another part was my tendency to lean on my right. Also I did once make a long cut down that one vein from my Big Toe to my Ankle.
Either way, I had my foot tied up in a brace for most of Junior year, on and off. I limped a lot and still refused to get an elevator key and 5 minutes between classes gave me just enough time to get up the stairs anyway.
But I digress. My foot only became a nuisance when I wasn’t allowed to work out during physical training for class. I could do every exercise on one foot, even if it wasn’t that graceful. They still made me sit out. As time went on, and my foot failed to recover from being stupid its injury, I was forced to take daily visits to the nurse. These visits were completely idiotic unhelpful as all she ever did was unwrap the bandages, comment that it wasn’t looking good and that I should see a doctor, and rewrapped the bandages.
All those unhelpful nurse visits: the reason I only lost 4 pounds a week and still don’t know what went on in Spanish class. Ever.
