Hi I am having shoulder pains which are really affecting my sport perfomance I can bowl a ball in cricket but cannot throw what can I do?

Possible labral tear. In addition to problems with the rotator cuff, throwing athletes can injury or tear a cartilage structure inside the shoulder called a labrum. Rehab or surgery may be helpful.
Rotator cuff rehab. Shoulder pain during overhead activity is rotator cuff impingement and tendon degeneration until proven otherwise. Classic. Avoid painful abducted shoulder positions (that is, anything with elbows out to sides). Do cuff and scapula muscle strengthening until normal. Try a bursal injection. Mri. May need arthroscopy if nothing else works. Avoid all that causes grinding, popping, or pain.
