I play basketball and last Friday during practice we were sprinting and I got a pain in the outside part of my left calf. I thought it was just a cramp so I kept running but the pain is still here a week later. I've been icing it for about 20 minutes a day, and on Monday and Tuesday I sat out at practice. On Wednesday I practiced because it felt a little better but it hurt afterwards. Same thing with the game we had today. Please let me know what this may be and what I need to do to get it better
