What Are Those Splotches?

See those red splotches on my leg? That's cellulitis. It's a skin infection caused by a bacteria. If left untreated, it can get into the blood and cause sepsis, which can be deadly. This is the second time I've had cellulitis in less than 6 months. Both incidents seemed to stem from an injury to my leg. The first time I ran into a cabinet door; this time I hit it with a chair leg. Nothing happened for a week, then, suddenly, the red blotches appeared. I thought it was a blood clot, but an ultra sound proved otherwise. This can be treated easily with antibiotics, and I've been taking them, so I should be good as new in ten days.
