In a soccer game, I slid on the turf ground and scraped up/opened up my knee. It s a topical injury, it s not deep. However, in the days after the injury, the area surrounding the cut as well as up my thigh had been hurting. My knee began to hurt internally as well. Today, I noticed that bumps or pimples starting forming up my thigh starting from where the injury is and creeping up my leg. Should I see a doctor about this? I m not sure if it requires medical attention.
