How many times has your foot(or leg) 'fallen asleep'? How annoyed have you been by waiting for it to 'wake up'? Wait no further! I have a tried and true way to fix this annoying ailment. It's very simple. First, from what I have learned this odd phenomena happens when the nerve channel has been 'pinched off' long enough to prevent the flow of ions that relays the message to your brain(feel free to correct me if I am wrong). The tingling sensation is the eventual reestablishment of the the ion transport that is indicative of normal nerve function. So how could one get the ions flowing again so you don't have to suffer the annoying and sometimes agonizing pain of 'sleeping feet'? Easy, pump the nerve channel to promote the ion flow. For your foot it is real easy. Do the following next time your foot 'falls asleep'. On the back of your calf where the two muscles comes together there is a 'pressure point' that when pushed will pump those ions, this area is associated with the 'sciatic nerve'. It is easy to locate because it is very sensitive and when you press it you will feel a some pain. I am sure there are others here who could give a much better description than myself. I figured this out when I was learning martial arts, we were covering pressure points and how to use them against your opponents. I had recently came across some material that discussed why your foot or other limbs 'fall asleep'. Well I put two and two together and had an idea. So the next time I was in class taking notes and my foot 'fell asleep' I tried my new fangled notion and it worked. Give it a try, I just did it sitting here reading the internet and that is what prompted me to pass it along. So let me know if it works for you!
