Welcome to bike forums! Sorry to hear of your problems. This thread seems to get resurrected every year or two. Since your problem is a bit different than the original topic, and isn't related to commuting specifically I suggest you start a thread in a more appropriate sub-forum like road cycling or training and nutrition. You can see a list of all subforums on the main bikeforums.com page. Hope you find answers.
But, while you're here...
Since you're 16 and probably still growing, I wonder if your intermittent pain is related to your muscles being stressed by growth spurts in the femur etc, but that may be completely wrong.
Also my understanding is that CK is a sign of stressed muscles, but it still doesn't explain why they are stressed.
