sounds like fun...! (i know at least eight people who are definitely suffering from this)
In Münchausen syndrome, the affected person exaggerates or creates symptoms of illnesses in themselves in order to gain investigation, treatment, attention, sympathy, and comfort from medical personnel. In some extremes, people suffering from Münchausen's Syndrome are highly knowledgeable about the practice of medicine, and are able to produce symptoms that result in multiple unnecessary operations. For example, they may inject a vein with infected material, causing widespread infection of unknown origin, and as a result cause lengthy and costly medical analysis and prolonged hospital stay. The role of "patient" is a familiar and comforting one, and it fills a psychological need in people with Münchausen's. It is distinct from hypochondriasis in that patients with Münchausen syndrome are aware that they are exaggerating, whereas sufferers of hypochondriasis believe they actually have a disease.
