I am an 18 year old male, and I run cross country and track & field for my college. I've been running since I was in middle school. Last year during cross counrty I experienced a deep pain in my right quad. I ignored it thinking it was soreness. I also noticed that my times were getting slower and slower. After a month I knew I needed medical help. My doctor drew blood and informed me that my CPK levels were close to 1000, but he didn't know what was going on. I sat for about two months, only to come back and run into the same problem, but worse. I took another month off and ran into same problem again. But this time it was in my left leg. I'm not what this is, but I need help before I start my second season.View Thread
