Achilles?

It was recently that I started to feel a slight pain on my left foot. It's really nagging and sometimes, I can't even walk straight!! It was only today that I asked a medical student friend of mine and he said the place of the pain is the Achilles tendon. I was like @.@

For those of you who do not know, a ruptured Achilles tendon means that you will be out of sports for a few months, possibly more. David Beckham isn't able to play in World Cup '10 because he ruptured his Achilles tendon a few months ago in an AC Milan game. That is how much trouble a ruptured Achilles tendon can cause

As it is, I believe it's only a sprained Achilles tendon at most. I have a half-marathon to run in 2 weeks and a full-marathon to run in 1 month. Now I'm not even sure if I'm physically fit to run 21km >.<
