For question 1 it's just a biochemical response from thermoreceptor nerves in the skin, temperatures that are likely to cause lasting damage from prolonged exposure cause a neurological response - in this case it's pain. In address to question 2 it is most likely down to the physiological response of vasoconstriction. When the body is cold the body ...

It doesn't matter if its hand or any other human body organ, cold would hurt, the reason being that we humans being warm blooded animal require an optimal temperature-pressure balance to be maintained for our nervous system to work in its natural order. So when we have, in your case, cold hands its like a thermal shock to our hand as the above mentioned ...

Typically nerve compression or a "pinched" nerve is due to inflammation in the tissue through which a nerve passes. The gap is already quite narrow so any inflammation is quite potent. Inflammation causes you to feel things as more painful (hyperalgesia). In a similar way to how of you burn your hand then poke it, it hurts, when cells are damaged the ...

It has to do with the way that body parts are more rigid when it is cold. This makes them less flexible and more prone to superficial injury....even without frost nip setting in. In the event that actual frost nip set in, this would be even more sensitive, as you have tiny crystals beginning to form in your cells, like little shards of glass......and, ...

As AndroidPenguin described the nociceptive pathways are activated by inflammation or noxious chemicals. Sometimes pain can arise independent of active nociceptive pathways. Most evident in cases of Neuralgia and perhaps in case of Pseudoneuromas. In certain cases the injured nerve causes disinhibition of the pain pathways arising from the dorsal horn of ...
