So yesterday I was playing dodgeball in gym(dominated) and while I was making an epic dodge, I smashed my knee on the basketball floor. At the time I felt a sharp pain that lingered for about 10 minutes after hitting it. Now with it being over a day later, it still is red(I know it takes time to heal) and when even the slightest thing touches it, I feel a shock of pain. I also do not have any pain walking or when I move it. Does anyone have any suggestions for home remedies that will help it heal faster?
