I've been having the strangest sensation in my left leg. I wanted to see if anyone else has ever experienced this, too.

If I turn my head to the right and then look down (like looking at the floor) I can feel my left leg go completely weak. No buzzing or vibrating feeling....just weak. It's the weirdest feeling. I usually notice it when I'm sitting at the computer but I tried it while standing and my leg nearly gave out on me! I can almost feel the muscle relax to the point of not being able to hold me up.

Could this be caused by a lesion on the spine? I'm not freaking out about it....just wondering if this is something comparable to the buzzing, vibrating feeling that happens when you touch your chin to your chest. I cannot think of the term for that......it's on the tip of my tongue.
