Symptoms:

Tennis elbow or golfer’s elbow is the inflammation on the upper arm, both inside and outside the elbow.

Cause:

Repetitive motion is one of the leading causes of tennis elbow.  The symptoms begin gradually, starting as a dull ache and comes and goes.  This will progressively get worse and eventually the paint does not go away.  Every time the pain happens, it continues to traumatize the tendons, creating more pain with micro tears.
