You run cross-country?! I ran in high school. I thought about running in college, but the coach was a slave driver. Too bad I got sick. I got this thing called polycystic ovarian syndrome, it causes an imbalance in hormones and makes you gain weight and makes it even harder to lose.
I know all about injuries and recovery from running, though. I ran so much my sophomore year that I got stress fractures in both of my heels. I just thought my feet were sore from my shoes, so i bought new ones and kept running. After a month I couldn't even walk on them. When I went and had x-rays turns out the stress fractures had cracked straight through both of my heel bones! While I was recovering I did a lot of upper body work, and resistance free lower body work (i.e. leg lifts, flutter kicks, scissor kicks, etc). Maybe refocusing areas and working on toning will help for now....?
