definition of Pain:

Pain is an integral part of the defense system of the body. It signals that something is wrong, and helps to minimize the physical harm that is done to the body. In the majority of cases, when a person finds something to be painful, they react in such a way to alleviate the pain, resulting in the harm to their body being minimized; however, in certain individuals, the pain is either not felt, or no reaction is observed, resulting in more harm being done to the body

Name of the disease: Congenital analgesia

definition : Congenital analgesia, also known as congenital indifference to pain, is a rare condition in which there is an absence of pain sensation from birth without the loss of other sensations or demonstrable nerve pathology (2). This can result in the individual unintentionally harming him or herself, or in an injury being made worse by the individual not realizing its severity. The first report of the condition was made in 1932, concerning a man who acted as a human pin cushion. Since then, there have been fewer than 100 reported cases in the United States (3). The exact cause of the condition is unknown; the nerves appear to be normal and functioning properly in the majority of cases. The condition is believed to be hereditary (2,, 3). The higher frequency of occurrence among the children of consanguineous parents suggests that the responsible allele is recessive, although there have been reports of what appears to be an autosomal dominant version of the condition. The reports of the autosomal dominant variation of congenital analgesia are too infrequent to come to any real conclusion at this time, but it is possible that the condition may be caused by more than one allele (5). Congenital analgesia is sometimes associated with auditory imperception, along with a trisomy of one or more chromosomes in the 13-15 group; however, this association is by no means proved .

yes there is 2akid it's a neurotrasmitter but it can be called so "substance P" or "substance pain"

In neuroscience, Substance P is a neuropeptide: a short-chain polypeptide that functions as a neurotransmitter and as a neuromodulator. It belongs to the tachykinin neuropeptide family.

Pain
Substance P is involved in the transmission of pain impulses from peripheral receptors to the central nervous system.

How Substance P is Related to Pain

Nerve cells communicate with one another through neurotransmitters. Substance P is one such neurotransmitter. It is a protein found in the brain and spinal cord, and is associated with some inflammatory processes in the joints. Its function is to cause pain.

it is called substance P and not substance pain

Nerve cells communicate with one another through neurotransmitters. Substance P is one such neurotransmitter.
