Not only golfers and tennis players suffer from arm and elbow injuries, cricketers are often similarly affected.
Improper batting, throwing/bowling techniques, as well as incorrect or a change in equipment, such as bats that are too light/heavy, put unnecessary strain on the forearm.
With all the different formats of the game like 20/20, tests and 50-over cricket at international level, some players have resorted to using two different types of bats: a heavier one for the shorter versions of the match, and a lighter one for the tests. [This constant changing between the two different bats also aggravates the elbow tendons, causing injury.]
Other possible causes of elbow pain would be a batsman attempting to use his wrist to flick the bat, change his bat weight, or make the grip too small or big.
