Algesia refers to the ability to perceive pain, and hyperalgesia is when pain levels are higher than expected. Causes include nerve damage, psychiatric conditions, and drug use. Analgesics are drugs designed to reduce pain, including NSAIDs and narcotics. Pain is an evolved response to damage in the body and serves to protect the body from further injury.
Algesia is a scientific term that refers to the ability to perceive pain. Commonly, in medicine, the word is used to refer to pain levels higher than those expected from a specific condition. Causes include nerve and sensory receptor damage, some psychiatric conditions, and drug use. Medications that can help reduce pain are known as analgesics.
Pain is an evolved response to damage in the body. When a finger touches a hot surface, for example, heat damage to the skin is sensed by pain receptors on the skin. The pain stimulus passes the nerves to the brain, which tears the finger off. Even after the person has removed the finger, the damaged skin still produces pain signals, because the skin’s ability to protect the finger from health problems such as microbial infection is impaired. The pain, therefore, prevents the person from making the minor injury worse by using the finger.
Normally, each injury produces a specific level of pain, which places some level of restriction on the person’s movements and actions. A person with a broken toe can get to the hospital on their own, for example, while a person with a broken leg usually has to sit still and wait for help. The lowest level of pain with the broken toe allows for free movement, as the risk of further damage is low by moving around. Trying to walk on a broken leg, however, can cause serious damage and so the body produces a lot of pain to avoid it.
When a person experiences more pain than usual with a certain medical condition, this situation is often called algesia. It can also be known as hyperalgesia. A hypersensitivity to pain may be due to damage in the bodily systems that recognize pain, or it may be due to psychological factors, where the affected person has no physical reason for the increase in pain, but rather the psychological recognition of the pain is impaired. ache.
Since it is the sensory receptors and nerves that recognize and transfer pain information to the brain, it is these body components that are commonly involved in the conditions of algesia. People who have abused drugs of the opioid family, which includes heroin and morphine, may also suffer from algesia, as these drugs act directly on the body’s pain sensation system. A stroke can also produce abnormally high pain sensations, if the part of the brain that handles these pain signals is affected.
Analgesics are drugs designed primarily to reduce pain. Two main groups of these pain relievers are nonsteroidal anti-inflammatory drugs (NSAIDs) and narcotic drugs. Typically, NSAIDs such as aspirin and ibuprofen fall into the over-the-counter category, while narcotics, with their stronger effect, are more controlled. Examples of narcotics include codeine and morphine.
