Short version: My knees point in when my feet point straight. This makes it hurt when I run.
I'm currently 16. In 9th grade, I switched out of my public school to an independent study one. It's like home schooling, but I meet with a teacher once a week for assignments and do everything myself. It was half way through the year that I switched. I had been running in PE that year and never had any problems. I had finished PE, so it wasn't until a while later when I started running for my own health and not for school. I stretched properly and started off small, but my knees hurt when I stopped running. For a month or two I built up to three miles of slow jogging, but my knees would still hurt.
I started looking online and read something about crows feet, or a similarly named condition. Basically, my feet and knees aren't aligned properly. If my feet point forward, my knees point inward and will touch if I bend them. If my knees point forward, my feet point out. I hadn't noticed this before, but I wasn't looking either, so I don't know how long my legs have been like that.
I talked briefly with a friend of the family who also happens to be a personal trainer. He said that my thighs were a bit weak and showed me an exercise where I sit against a wall and have to strain my muscles to keep myself up. He also said to ice my knees, as there's probably swelling. I did both for two months and saw no change, so I switched to squats. I did those for a while and still didn't notice anything.
Does anyone know anything about this? What can I do?
