A study of 4,703 patients found that 26% had pain in the last two years of life, increasing to 46% in the last month.A survey of 6,636 children (0–18 years of age) found that, of the 5,424 respondents, 54% had experienced pain in the preceding three months. A quarter reported having experienced recurrent or continuous pain for three months or more, and a third of these reported frequent and intense pain. The intensity of chronic pain was higher for girls, and girls reports of chronic pain increased markedly between ages 12 and 14. Society and culture
Physical pain is a universal experience, and a strong motivator of human and animal behavior. As such, physical pain is used politically in relation to various issues such as pain management policy, drug control, animal rights or animal welfare, torture, and pain compliance. The deliberate infliction of pain and the medical management of pain are both important aspects of biopower, a concept that encompasses the "set of mechanisms through which the basic biological features of the human species became the object of a political strategy".In various contexts, the deliberate infliction of pain in the form of corporal punishment is used as retribution for an offence, for the purpose of disciplining or reforming a wrongdoer, or to deter attitudes or behaviour deemed unacceptable. In Western societies, the intentional infliction of severe pain (torture) was principally used to extract confession prior to its abolition in the latter part of the 19th century.
Nicotine withdrawal is a group of symptoms that occur in the first few weeks after stopping or decreasing use of nicotine. Symptoms include intense cravings for nicotine, anger or irritability, anxiety, depression, impatience, trouble sleeping, restlessness, hunger or weight gain, and difficulty concentrating. Withdrawal symptoms make it harder to quit nicotine products, and most methods for quitting smoking involve reducing nicotine withdrawal. Quit smoking programs can make it easier to quit. Nicotine withdrawal is recognized in both the American Psychiatric Association Diagnostic and Statistical Manual and the WHO International Classification of Diseases. Signs and symptoms
The most documented symptoms of nicotine withdrawal are cravings for nicotine, anger or irritability, anxiety, depression, impatience, trouble sleeping, restlessness (psychomotor agitation, including indeliberate movement), hunger or weight gain, and difficulty concentrating. Symptoms are usually strongest for the first few days and then dissipate over 2–4 weeks. The most common symptoms are irritability, anxiety, and difficulty concentrating. Depression and insomnia are the least common. Other withdrawal symptoms may include anhedonia, constipation, cough, decreased positive affect, dizziness, drowsiness, headache, impulsivity, fatigue, flu symptoms, mood swings, mouth ulcers, and increased dreaming. Cessation of nicotine can also require changes in levels of various medications. Definition
