REASONS WHY YOUR LEG SLEEPS AND FEELS LIKE PINS AND NEEDLES___SCIENCE EXPLAINED

You sit down to press phone or watch film. You sit for long time with your leg folded. When you want to stand up, your leg does not want to stand....It feels heavy, tingling, like thousand ants walking inside. Like pins and needles.

We call it "leg don sleep" but your leg did not sleep. What happened is your nerve was pressed.

How it happens?

In your leg there is a long nerve called sciatic nerve and other small nerves....Their work is to carry messages from your brain to your leg and from your leg back to your brain. They tell you when to move, when something is hot, when to feel pain.

But when you sit with your leg folded, or you sit on top of your leg, or you cross your legs for too long — you press that nerve....You squeeze it like you squeeze a water hose.

When you squeeze a water hose, water stops flowing...Same thing with nerve. The messages stop flowing well. The nerve cannot talk to your brain properly.

At the same time, you also press small blood vessels. So blood cannot reach that area well to give oxygen.

So your brain starts receiving confused messages. Instead of normal feeling, you start feeling tingling, prickling, numbness....That pins and needles feeling is your nerve trying to wake up and start talking to your brain again.

That is why when you try to stand, it is even worse for few seconds. The nerve is now getting blood again, it is firing many signals at once to your brain. Your brain does not understand, so you feel that electric shock, peppery feeling.

After you shake your leg, walk small, or change position — blood flows back, nerve starts working normal, and the feeling disappears. Usually in less than 2 minutes.

Is it dangerous?

If it happens once in a while because you sat for long, it is normal. Everybody experiences it.

But if your leg always feels pins and needles even when you did not sit on it, or it stays for long time, or it comes with weakness — it can mean nerve problem, vitamin B12 low, diabetes, or back problem. Then you need to see doctor.

How to stop it?....:👇

Do not sit in one position for too long....If you sit to read or press phone, stand every 30 minutes. Do not fold your legs under your body. If you cross legs, change sides. Exercise your legs small.

Your leg did not sleep. You just pressed the wire that carries message. Release the wire, and your leg wakes up.

Have you ever tried to run when your leg was still sleeping? How did it feel?
