Why do we get pins and needles?
Thanks for asking.
We all know what it feels like to get pins and needles.
It usually happens when we've been in the same position for too long, sleeping on one of our arms, for example.
Bad posture when seated can make this more likely to happen.
It's a slightly uncomfortable feeling of numbness and tingling.
As if someone was raking your skin repeatedly with small pointed objects.
That's where the name pins and needles comes from, which goes back to at least the mid-19th century, according to worddetectivecom.
By the way, there is a scientific term for the sensation too.
Parasthesia.
Where does the pins and needles reaction come from?
It's actually caused by changes in nerve function.
Pressure is the most common cause of pins and needles.
When you sit or sleep on a part of your body, you squeeze the nerves and blood vessels that are there.
This reduces the flow of blood and oxygen, which makes the nerves send abnormal signals to the brain.
You feel these signals as pins and needles.
The most common body parts to get pins and needles in are the hands, arms, legs and feet.
The sensation usually goes away quickly when you remove the pressure and restore blood flow.
Injury or disease can also affect nerve function and cause pins and needles.
For example, if you have nerve damage from an accident or you have certain other health conditions, you may have pins and needles that last longer or affect different parts of your body.
What are some examples of those health conditions?
Pins and needles can result from diabetes.
When the level of sugar and fat in the blood is too high, it can damage the nerve endings.
That's known as diabetic neuropathy and it results in tingling in the limbs.
People with multiple sclerosis, an autoimmune disease that affects the central nervous system, may experience pins and needles in various different body parts.
In what cases should I be worried about pins and needles then?
If you have pins and needles that last a long time, keep coming back or affect different parts of your body, you should see a doctor to find out the cause.
That's especially true if you're experiencing other symptoms too, like vision problems or muscle weakness.
Your doctor will likely carry out some tests and give you the right treatment if needed.
So don't panic if you have pins and needles once in a while, but don't ignore them if they're persistent or unusual.
