Whenever I throw a ball in baseball style, My shoulder starts hurting. Pain is very point-ish and it feels something stabbing my muscles from inside for 20 seconds to 5 minutes based on my efforts I have this problem for years. I usually play in Summer breaks so I have this problem every summer breaks which means it is not healing by itself. The pain only occurs when I throw the ball in baseball action, When I throw the ball in Cricket action or lift weights, No pain occurs.
