The area between my knee and my thigh

[TheRisenUndead]

I think it just started yesterday when I was kinda trying out my ankle weights.... Now, for my left leg, the area between my knee and my thigh would slightly hurt whenever I started walking.... Weird thing is, if I were to jump, or do a quick stationary sprint ( sprint at one spot and remain there), or do some stretching with my left leg, it WOULD NOT hurt..... Only when I'm walking, it begins to hurt... Any idea what the problem is? Could this be due to the fact that I was forcing on myself ankle weights which were too heavy for me to handle which made this little ache that will vanish in a short while?

I would say, try a doctor...
