According to this excellent answer, the difference between "pain" and "pins and needles" (neuropathy) is that different receptors (sensory nerves) trigger in reaction to different stimuli.
Different types of pain receptors (hot/cold, pressure, etc.) send pain signals to the brain.
Different receptors are responsible for sending neuropathy signals to the brain. These receptors are usually triggered when the nerve receives a shortage of blood flow.
According to the Wikipedia Article on Sensory Receptors, there don't appear to be any nerves that produce pins-and-needles sensations to the brain...
So I ask: What are the specific types of nerves/receptors that send "pins and needles" signals to the brain? What are they called?
I would imagine that it either has to be a specific, specialized receptor that (perhaps) starts firing if its senses "something is wrong" (such as decreased bloodflow to the area, etc.), or it's that all sensory receptors are capable of firing "pins and needles" signals under special circumstances.
