One is that of ergonomics, the changing of ones environment (especially workplace equipment) to minimize repetitive strain. General exercise has been shown to decrease the risk of developing RSI. Doctors sometimes recommend that those with RSI engage in specific strengthening exercises, for example to improve sitting posture, reduce excessive kyphosis, and potentially thoracic outlet syndrome. Modifications of posture and arm use are often recommended. History
Although seemingly a modern phenomenon, RSIs have long been documented in the medical literature. In 1700, the Italian physician Bernardino Ramazzini first described RSI in more than 20 categories of industrial workers in Italy, including musicians and clerks. Carpal tunnel syndrome was first identified by the British surgeon James Paget in 1854. The April 1875 issue of The Graphic describes "telegraphic paralysis. "The Swiss surgeon Fritz de Quervain first identified De Quervains tendinitis in Swiss factory workers in 1895. The French neurologist Jules Tinel (1879–1952) developed his percussion test for compression of the median nerve in 1900. The American surgeon George Phalen improved the understanding of the aetiology of carpal tunnel syndrome with his clinical experience of several hundred patients during the 1950s and 1960s. Society
Specific sources of discomfort have been popularly referred to by terms such as Blackberry thumb, PlayStation thumb, Rubiks wrist or "cubers thumb",  stylus finger, and ravers wrist, and Emacs pinky. See also

In rare cases, anticoagulants can cause hemotympanum with no underlying cause or injury. Experiencing a head injury while taking anticoagulants, increases the likelihood of hemotympanum. Ear infections
Frequent ear infections, ongoing inflammation and fluid buildup can increase the risk of hemotympanum. Treatment
Skull fractures usually heal on their own, but they can also cause several complications. Cerebrospinal fluid leaking out of the ear involves a higher risk of developing meningitis. Treatment may include corticosteroids, antibiotics, or surgery. == References ==
