Shane Doan has Rocky Mountain Spotted Fever (an actual illness)

This disease is caused by Rickettsia rickettsii and is transmitted by a number of different ticks. Despite its geographical title, Rocky Mountain spotted fever is present in many locations throughout the United States and the entire Western Hemisphere. After infection by tick bite, there is an incubation period of 2–14 days. The abrupt onset of the disease includes severe headache, fever, chills, arthralgia [joint pain], and myalgia [muscle pain]. After 2–3 days of these constitutional symptoms, erythematous macules [spots] erupt on the wrists, hands, forearms,legs, and ankles ... Lesions then spread to the palms and soles and the trunk. The macules originally blanch with pressure but soon become purpuric [subcutaneous bleeding] and even necrotic [dead skin tissue]. The disease causes a severe vasculitis [inflamed blood vessel(s)] and complications include disseminated intravascular coagulation [proteins that control blood clotting become over active], hemorrhage into the gastrointestinal and urinary tracts, and cardiovascular collapse.
