Sharp Leg Pain

So I have been experiencing this sharp pain in the front of my legs,its up high like right next to where my junk is but right in the center of my leg.It hurts when say i lift my legs up or start to walk or even squat.

How long has this pain been present for? If only a few days it could just be muscle strain, if longer it may be related to a tendon or ligament in your hip. Try (slowly and easily) performing the foot-elevated hip flexor stretch, to check pain and flexibility levels in your rectus femoris.
