Pain

Pain is a distressing feeling often caused by intense or damaging stimuli, such as stubbing a toe, burning a finger, putting alcohol on a cut, and bumping the "funny bone". Because it is a complex, subjective phenomenon, defining pain has been a challenge. The International Association for the Study of Pain's widely used definition states: "Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage." In medical diagnosis, pain is a symptom.

Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future. Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. Simple pain medications are useful in 20% to 70% of cases.

Pain (philosophy)

Philosophy of pain may be about suffering in general or more specifically about physical pain. The experience of pain is, due to its seeming universality, a very good portal through which to view various aspects of human life. Discussions in philosophy of mind concerning qualia has given rise to a body of knowledge called philosophy of pain, which is about pain in the narrow sense of physical pain, and which must be distinguished from philosophical works concerning pain in the broad sense of suffering. This article covers both topics.

Historical views of pain

Two near contemporaries in the 18th and 19th centuries, Jeremy Bentham and the Marquis de Sade had very different views on these matters. Bentham saw pain and pleasure as objective phenomena, and defined utilitarianism on that principle. However the Marquis de Sade offered a wholly different view - which is that pain itself has an ethics, and that pursuit of pain, or imposing it, may be as useful and just as pleasurable, and that this indeed is the purpose of the state - to indulge the desire to inflict pain in revenge, for instance, via the law (in his time most punishment was in fact the dealing out of pain). The 19th-century view in Europe was that Bentham's view had to be promoted, de Sade's (which it found painful) suppressed so intensely that it - as de Sade predicted - became a pleasure in itself to indulge. The Victorian culture is often cited as the best example of this hypocrisy.

Pain (musical project)

Pain (typeset as PAIN) is a musical project from Sweden that mix heavy metal with influences from electronic music and techno. The project started out as a hobby project for front man Peter Tägtgren, whose idea was to fuse heavy metal with 1980s-inspired electro-industrial and techno influences. Tägtgren, who is also the vocalist/guitarist of Hypocrisy and producer of his own The Abyss studios, is the only current member.

Pain's self-titled debut was released in 1997, and since then Pain has released six more albums and a DVD. Starting with their second, all of Pain's albums have made the Swedish charts, thanks in large part to hit singles such as "End of the Line", "Shut Your Mouth", and "Same Old Song". In early February 2006, Blabbermouth.net reported that Pain had signed with Roadrunner Records. Currently, Pain is under the Nuclear Blast Records banner.

In 2008, Pain was on tour as a supporting performer for the Finnish symphonic power metal band Nightwish. During this tour singer Peter Tägtgren, drummer David Wallin, and bassist Johan Husgafvel were assaulted by a gang in Leipzig. Tägtgren received 10 stitches in his face, Wallin suffered a concussion and stitches to his head, and Husgafvel had his nose broken.
