After playing today I noticed that my right leg was experiencing a very slight soreness. This has never happened to me, and it isn't serious at all, but I'm just curious about what caused it. It's not the type of pain that you'd experience from a fall or a pulling of a muscle but it's just a dull-ish soreness in the middle of my thigh. Sort of like when someone charlie-horses you. Or when you're snowboarding and your legs get sore from carving too much.
