So I have these bruises on my leg and well I haven't really been paying attention to how long I've had these bruises but I have quite a few on the bottom part of my left leg and one huge one on my knee area on my right leg. They've been there for awhile and I don't know how I go them. I'm thinking it might be from working out since I just recently started working out about 2 weeks ago and they are mostly leg exercises that I do. Does anyone know if you can get bruises just from working out?
