What is wrong with my leg?

My leg has been giving me problems for about 2 weeks now. I went in to my doctor and she couldn't figure out what exactly was wrong. The first symptom was a weird pressure feeling around/on my tibia, approximately in the middle of my tibia. Every time I would step down or land (I skateboard) I got the weird pressure feeling in that spot. I made the mistake of going to the skate park, later that night my other symptoms occured. My foot went numb, I couldn't feel anything and it got really heavy, every once in awhile I got that tingly sleepy feeling but not often. It stayed numb for quite a few days, and still gets numb out of nowhere every once in awhile. On top of that my ankle started hurting, and a shooting pain comes up from my ankle. My doctor suggested a stress fracture (didn't do x-rays because she said most don't show up anyways), some syndrome with my nerve in my foot, and possibly damaged main nerve in my leg, which is effecting the surrounding area. She left everything basically wide open, with no questions answered, and many possible scenarios. I often get a weird feeling that a muscle in my leg is being pulled when I am sitting and lift my heel off the ground (if you were to shake your leg, if that helps with the imagery). That feeling of a muscle being pulled is left of that weird pressure feeling. So many things are going wrong that I have no clue what to do, I don't know who to see that would know anything about this either. It has been about 2 weeks of this constant numbness/pressure feeling/pain/ and pulling feeling, all I know is that something is deffinetely wrong with my leg. I can still walk fine but it is aggrevating. Please anything will help me! Even suggestions of a type of specialist I could see that might know what is going on?
