My anatomy and physiology professor had the best way of describing this, a kinked hose where the pressure is finally released. She had us actually sit on one of our feet for several minutes and had us all stand up and attempt to walk around. Incredibly hilarious woman and a fantastic professor

The tumor part explains why I had numbness close to the place of a fat tumor that was removed through surgery.

If I bend my spine or neck for long periods of time, when I move them to the neutral position there's this awful burning sensation. Is that normal?

...I actually like the feeling of pins and needles. Anyone else?
candymountainn (3 months ago)
I thought the nerves physically get squished, and they send garbled messages back to your brain which equates to the pins and needles feeling? no?

Once had to sit on the floor as part of a school assembly, because of the cramped seating my leg went dead but I couldn't move to release it - and then I had to walk and my foot was visibly unresponsive and heavy; not great
SKB Artistry (4 months ago)
In Denmark we describe it as my leg or my arm "is sleeping". Oh, and hitting the funny bone is usually called "getting stunned" or "getting a shock up/down through my arm" or "my leg"

When you sit on your phone on the toilet for too long.

Friendly reminder that if you ever are in a situation where you have to stand for a long period of time, don’t lock your knees. The restriction of your blood flow can make you pass out.

So... If that's what's happening to my arm/leg/hand/foot... Why does continuously waving the unfortunate limb around make that feeling go away?

STORY BOUT MY LITTLE FINGER (for the people who do/do not care :)) just a couple minutes ago my left hand got pins and needles and my little finger went proper NUMB. no tingles, just numb. I felt that finger with my right hand and I couldn't feel myself pinching it. instead of me feeling like I was touching my finger it felt like I was touching a rubber sausage or something. I'd wiggle that left little finger with my right hand and it was so weird. I gotta admit I also bit my finger and I bit harder and harder and them suddenly I felt it, but still it was weird.

Danielle Howe (8 months ago)
I used to get pins And needles for one of my medication, stopped taking it because the face tingling was a bit much
how I fix this problem when my small finger falls asleep from not using it to type is dunk it in some cold water. Usually works.
i have a question for a video: Why does that area right below your ear sometimes hurt when you chew something or smile?
Travis Negrete (8 months ago)
I had arm surgery that damaged my ulnar nerve so I have partial numbness in my arm. When I hit my funny bone, after the pins and needles goes away my nerve damage is more severe and wide spread in that arm for a few hours before returning to normal. Normally only the back side of my arm is numb but when I hit my funny bone even the back side of my hand gets numb, really scary! Why is this?

I was sleeping in a car using my arm as a pillow. My arm was bent with my hand supporting my head and my elbow on the arm rest. I did this for 1 hour and my arm was numb for a LONG time.

What if you really like the feeling of pins and needles? Can you cause serious damage if you intentionally trigger it somewhat regularly?

I usually shake my limb or smack the area. It seems to make it go away faster.

Who else got paresthesia watching this while sitting on a toilet in the thinker position
light564 (9 months ago)
Forgot one more thing, while you're standing up rub your legs or the affected area in a downward motion Or if it's the arm rub It gently so that you're going towards your hand. You'll notice a cold sensation and the feeling will return faster. Also you can have that pens and needles feeling when you lose all feeling in your appendages because you're cold

I'm confused, I've been diagnosed with CPTSD but have also been diagnosed with spinal nerve compression, bulging disk and b12/iron/vitamin D absorption problems as well as reflux and in the past has surgery on colon which is when my mental health changed drastically, very difficult to pinpoint which is what. Recently I've felt very panicked about my future because of some relationship and housing and work issues but also was sat working for a couple of days with limited movement, so hard to pinpoint if mental health is setting this off or stillness. I feel extremely stiff the more I've exercised and tickling sensation underneath the skin near my spine but now it's all over my body if I sit for longer than a minute which is difficult when you need the toilet or to sit at a laptop. Anyone similar?

Jesus. If I had chronic paresthesia, at that point I’d probably rather kill myself.

During night I felt pain in my right eyebrow and it was strong, felt like needles, and I just tossed and turned until I realized it was too painful and it wouldn't go away so got up from bed and it slowly went away. I felt a little pain in between my eyebrow and my nose and it comes and goes. I don't know if I should take this seriously. It didn't feel like when a leg gets numb and tingly, people think that's what I mean, it felt like straight up needles.

Im scared now because I always sleep weird...what if 1 day I wake up and my arms and legs stay numb forever🤤😲

I get pins and needles regularly and if it has been long enough wherever it was gets paralyzed for a few minutes. Circulation problems aren't fun
The Microwave (9 months ago)
There was one time where I woke up in the middle of the night and my arm was so stiff. I tried to move it but it hurt so much and it felt like something was keeping my elbow from moving like the hinge it should've been. I managed to work out the problem but it left my arm real sore

I know the pins and needles you feel from a shot of heroin/morphine is caused by histamines. Its interesting that the tingling feeling is basically like static interference for your brain haha damn!
