You've got to throw the ball hard, you feel like you're impervious to injury and you push hard. So many times you end up straining or stretching the muscles by not exercising or by not turning the shoulder properly when you pitch. To avoid muscle damage, you should begin throwing gradually, stretching the muscle and using ice packs after the activity for usually three or four weeks. If you are unsure about mechanical movement, ask someone to check your stance. In older players, bursitis and tendinitis sometimes result from overuse in baseball as well as other sports.
Strains often cause microscopic tears in the ligaments.
After such injury, you should suppress the inflammation with ice. Heat is seldom recommended to treat an acute injury. Ice packs should be applied for 20 minutes at one and a half-hour intervals. Anti-inflammatory medication may also be necessary. After the pain eases, you should quickly try to restore normal function by returning to play within your comfort zone while gradually increasing the intensity of the activity.
