Hello! I work as a doctor for 21 years. My name is George O. Sapego. This article will talk about how and what appears abdominal pain and how this pain is distributed in an unexpected place.
We abdominal have receptors that respond to mechanical and chemical irritation. The main cause of pain in the abdomen - is stretching something. In addition to stretching are still other mechanical stimuli:
- swelling;
- reductions;
- tension;
- compression;
- torsion.
Nociceptors that perceive all this irritation, are usually in the serosal (outer) shell of the internal organs, and organs in the mesentery in the wall of hollow organs.
Those receptors that are in the mucosa bodies respond predominantly to chemical stimuli. All other pain receptors react and chemistry, and mechanical stimulation.
I still do not quite understand, due to what we are starting to feel the pain in the abdomen. Most likely, our brain decides for himself which signals from abdominal pain to consider, and which are not considered.
For example, the gastric mucosa is not sensitive to pressure and chemical irritants. But if there is inflammation, then it starts to feel all this in the gastric mucosa.
The threshold when our internal organs decide that finally they have the right to get sick, it is very different for different people and for different diseases.
Localization
The nerves in the abdomen are arranged so that the exact source of the pain is difficult. But there are certain rules:
- Most of the cases, the pain from the stomach and intestine is localized on the midline of the abdomen vertically. This is due to the fact that there are nerves and symmetrically on the right and the left.
- If the pain is particularly the one hand, it can hurt the kidney or ureter, or ovary, or the rare case when the nerves to the body fit for some reason only one hand. Exceptions to the rule - it is the gall bladder, ascending and descending part of the colon. These nerves are suitable for both sides, but most of it is on the side where the body is located. There's usually hurts.
- Pain impulses from the viscera go to the corresponding segment of the spinal cord. Therefore, we feel the pain at this level. That is, for example, a painful loop of the small intestine can be moved around the abdomen, but the pain we We will be felt in the navel region, because at this level of the intestine nerves enter the spinal cord brain.
synalgia
Sometimes, the pain from the internal organs extends far in some way. Sometimes that hurts is not that place.
I had a patient who complained of pain in the neck. His ambulance drove all night to hospitals. Otolaryngologist with purulent surgeon just inside Man is not twisted, but found nothing. But I had found pneumonia. Because pneumonia is just such a referred pain. You can read the story at the link below.
Referred pain associated with the spinal cord. The same spinal cord segment, which includes the nerves of the internal organs, is responsible for the sensitivity of the skin. Nerve impulses are mixed, and our brain think that the stomach does not hurt, and it is this area of the skin.
For example, in case of problems in the gallbladder begins to ache blade. This does not mean that the inflammation of the gallbladder seared belly up to the back. Just nerves from the gall bladder and the nerves of the blade peremknulo in the same segment of the spinal cord.
Referred pain is usually felt closer to the body surface. Rather, even in the skin.
There are two more characteristic referred pain:
- Increased skin sensitivity. People complain that they have "skin hurts."
- Tension of the abdominal wall muscles. It is from that in patients with peritonitis abdomen becomes rigid as a board.
Now, when you are grounded in theory, tell me: can hurt the liver, spleen, and mucosa of the stomach?
