My roommate has a fever and has been vomitting. He spent all day yesterday sleeping. He felt okay until after his shower and then a strange discoloration occurred on his right leg. he says it feels like it hurts on the inside. He just threw up again. I asked if the pain was sharp or throbbing and he said he guesses throbbing would be the closest explanation. The leg is also swollen. He has no known injuries or medical conditions.
