This is the painful condition of the elbow caused by overuse of arm, forearm and elbows. The term has become quite popular as the legendary cricketer Sachin Tendulkar was suffering from this condition and he has undergone surgery to fix up this condition.
It is most commonly seen in the professions where there is a constant use of arms, forearms, wrists and elbows. Apart from sports like tennis it is seen in carpenters, painters and plumbers. In medical terminology, it is called the lateral epicondylitis.
