question: I believe I tore my hamstring while sprinting in the sand on the beach. My leg planted deep in the sand an it was a sudden severe pain that knocked me down. My bruising a couple of days later goes from my calf to my upper thigh and I can t straighten my leg out when I walk w/o pain. I was assuming it to be a grade 3 tear.. Any suggestions? And what is the best treatment this first couple of weeks? Should I wrap it w/an ACE bandage to keep compression on it?
