Shin Splints. I started off on one of my many walks with shin splints. They were excruciating. I'd take a step and stop -on and on like that until I made three miles. I could barely limp into the house. No pain was worse than the self - loathing I felt if I didn't exercise. Anorexia is a disease of such INTENSE pain--physical, emotional--it is truly the definition of pain.
