Answer: Well pins and needles are caused from the lack of blood travelling to and from the body. for example if you put an elastic band around your wrist, eventually you will get pins and needle, because the blood doesnt travel to your hand due to the elastic blocking the veins. Pherhaps you get pins and needles on your tongue, because blood doesnt travel properly to it.
Answer: Tingling or pins and needles in the face and neck is likely caused by irritation of the cervical (C1-C4) nerves, Trigeminal nerve, or parts of the spinal cord, brainstem or brain responsible for the sensory component of the head and neck. It is impossible to determine the specific nerve without doing a proper neurological exam. A good chiropractor or neurologist should be able to perform the cranial/cervical nerve screening tests to determine exactly where the problem is.
Determining what the problem is with that specific nerve may be a bit more difficult. Sometimes orthopedic tests, imaging or bloodwork can identify the problem right away. Sometimes it is a matter of trial and error with therapies in order to determine a specific cause. Some of the problems that could cause tingling or pins and needles are: spinal joint dysfunction, herniated disc, vascular disorders, infections, poisoning, diabetes, epilepsy, multiple sclerosis, tumors, injuries, etc.
If a specific cause is not identified, a good course of action would be to try to treat the potentially simple causes first (eg: joint dysfunction or herniation) with conservative treatments (eg: manipulation). If conservative therapy to treat the problem is not effective, or the problem gets worse, then less conservative therapies (eg: medication/surgery) for potentially more complex problems (eg: infection or MS) would be indicated.

Constant pins and needles are a sign of bad circulation. It can also be a warning sign of diabetes and maybe other health issues. There is a natural vitamin called Gingko Biloba that can help with blood circulation around the body. Also massaging the area where the pins and needles are occurring is a good remedy.
Answer: No, only a complete idiot would even compare that to REAL pins and needles. So if you do think it feels the same way, get a big sticker that says complete retard and slap it onto your forehead. Congrats
This sensation seems to have many possible causes. According to eHow.com, posture, position, mineral imbalances, artery disease, nerve damage and diabetes are some of the causes.

Answer: Pins & Needles or the tingling feeling in your feet hands arms or legs that you get when you have been sitting in one place for a long time is caused by 1. Blood circulation speeding up & 2. pressure on nerves being relieved. Permanent pins & needles can have many causes but a compressed nerve is often the most common cause, a nerve conduction test will confirm or rule out a condition like that.
Answer: When you cut off circulation in your arms or legs, your hand gets numb due to the lack of blood. When you let blood go back into your arm or leg, the reaction feels like pins and needles are gently pressing against the area. This is also known as an arm or leg falling asleep.
