Stop Throwing the way you are throwing!!!!!!!!!!!!!
I had the same problem
the reason why you are felling pain in your elbow is now your elbow is having to take all the stress from the action of pitching.
eventually you will put to much stress on your elbow and cause a stress fracture in your elbow or rip the collateral ligament which runs from the wrist through the forearm to the elbow.
eventually resulting in a long time out or tommy john surgery
take it from someone who has gone through it
