Sounds Infected: For this you'll need to see a doctor right away. You might have an infection of the skin and adjacent soft tissue called a cellulitis but you could also have an infection of the knee joint called a septic joint which is very serious. In either case you don't want this one to get away from you so you should go to the emergency room now. You also need a tetanus booster if it been over 5 years.
