I'm a 6'3" 230 lbs. RHP and i had a twinge in my throwing shoulder. It is now basketball season and i haven't thrown in about a month. I have not felt any pain in any other situations. My dad, while at a physical therapy for my grandma asked the doctor about the problem. He said it was most likely a tight pectorial muscle causing the shoulder muscles to work harder and pinch together. is this a common alliment?
