What is the cause of pain?

Pain is a subjective feeling. People of different ages and genders have different ability to feel pain. Research shows that older people and women are more likely to feel pain. Even for the same person, the feeling of pain is not certain. People are more likely to feel pain when they are tired and stressed. In addition, the memory of pain may also affect how we feel about it. Many people's resistance to injections is probably related to their childhood experience of injections.

Of course, there are many objective factors that can also affect the degree of pain. For example, the type of stimulation, the content of potassium in extracellular fluid, some substances released by immune cells, and substance P near nerve fibers may affect people's perception of pain.

There are many ways to deal with pain, the most common of which is drugs. When choosing analgesics, we should not only consider the location and cause of pain, but also weigh the degree of pain and the side effects of drugs. Common analgesics are mainly divided into: non steroidal anti-inflammatory analgesics, central analgesics and narcotic analgesics represented by opioids.
