Pain in my leg--help please!?

It's a good idea to have it checked out.

If it's muscular, then it might be that the muscle keeps getting a signal to contract and re-contract itself. This can easily happen while sitting when we put our foot slightly behind the knee - that'll cause the muscle behind the leg to contract.

Animals naturally pandiculate... say what... they actually contract their muscles to allow them to release. They are not stretching, even if it looks that way. Go ahead and arch your back like a cat but pay attention to what it contracting... that's what healthy animals do... they sense tightness and stiffness and take it out.

For you, I can suggest for you to lie on your belly, then gently bring your heel toward the buttocks, that'll increase the tension behind the knee... then here's the key part... s-l-o-w-l-y release your foot down toward the floor. Then completely rest.

If you bump into pain or discomfort, then only bend the leg to where it is comfortable and no more.

Your leg may jump or hesitate on the way down... that's ok and normal if the muscles have been held at high rates of contraction. When you bend the leg again, once again release very slowly and rest... then the next time, lift with less effort and you don't have to bend the leg that much and notice if you can control the release a little better.

Just a few times is all it takes to reset the nervous system... otherwise you'd see animals holding those supposed stretches for a minute like un-knowing humans do.
