My muscles hurt what is wrong?

[hurst]

2 weeks ago we had a 600 meter run in school, i've lost so much weight since last year and achieved 149 seconds as my personal best :( still low. But when i finished it my muscles hurt so much i couldn't even sit down, i just breathed loudly and moved around. Now whenever i go play football (soccer) when i kick the ball with both of my muscles it hurts from the inside like im getting a cramp, could this be any injury ( i can walk perfectly with no pain)
Help please!

You probably pulled a muscle or something. You should go see a doctor and have them check it out and the reason why it does not hurt when you are running is because when you use certain muscles, like going to kick, it is a different muscle then when you walk.

Take a few days off, to let the muscles heal. Drink a lot, and maybe talk to a doctor about it, or a fitness instructor. Sorry. I think they were strained, which isn't anything that serious.

I think you might you have pulled your muscle that might be the cause of this pain.
