do people who don't have <for example> leg feel it?

Question

like u know they think they still have it and can feel pain hot cold etc

Answer 1

Yep. It's called phantom pain. This generally happens when someone has had to have a limb amputated. The mind & body still sense that the limb is still there. It can take a very long time for that feeling to stop. The pain that is felt is very real. It is hard to imagine that something that isn't there could hurt, but it does.

Answer 2

There are several different sensations that amputees may feel including:
- Phantom limb pain is pain that feels as though it is in the lost limb.
- Stump (residual limb) pain is ongoing discomfort at the amputation site.
- Phantom limb sensation is the feeling that the missing limb is still there. Although usually not painful, you may feel uncomfortable sensations such as burning, tingling and itching.

Initially, it was thought that these pains were psychological and treated as such however research has discovered other reasons for these discomforts including:
- Changes in nerve circuitry. Certain types of nerve damage or injury can increase your risk of phantom pain and the way in which your brain processes the amputation and the way in which it perceives pain changes.
- Pain before amputation. Some people who had pain in a limb before amputation have it afterwards, especially immediately after amputation. It's believed that this is because the brain holds on to the memory of the pain and keeps sending pain signals even after limb removal.
- Blood clot. A blood clot reduces how much oxygen gets to tissues causing tissue damage. The remaining tissue may take longer to heal than does healthy tissues or may never fully heal.
- Neuroma. A neuroma is a growth containing many nerve cells. A neuroma which forms on the nerve endings in a stump after amputation will cause painful nerve activity.

Of course there are many other factors which may help induce or even reduce your chances for suffering from pain or discomfort following amputation. There are several sites regarding phantom pain. A coupe of my favorite medical sites are the Mayo Clinic (www.MayoClinic.com), the Harvard Medical Journal (www.worldhealthnews.harvard.edu) and the John Hopkins University Medical Newsletter (www.johnshopkinshealthalerts.com).

Answer 3

People that have had limbs amputated often feel what is called "phantom limb pain" It isn't really understood why, but I think it has something to do with the "memory" of having nervous innervation in the limb by the brain. The brain is tricked into thinking it's having pain or sensation coming from the limb that isn't there.

Answer 4

Yes, sometimes. It's called phantom pain, and it hurts like it's still there. It's the nerve endings that send signals to the brain because they're traumatized by the injury.

Answer 5

yes if they had a leg before like the girl said, usually that leg was bad and felt pain before amputated so when they sleep they can remember that pain and the pain side of the brain is activated and they feel bad pain of the pain they used to have
