A little anatomy (or why does my elbow hurt?)
|Muscles of the back forearm|
A number of extensor muscles in your forearm meet at a single tendon that attaches to the elbow, the common extensor tendon. When your extensor muscles get strained, it will pull on that tendon causing pain at the elbow. No matter how much icy hot you apply to your elbow, the pain won't go away because the source of the pain is the forearm muscles.

Do these exercises often if you are prone to wrist and elbow issues. If you already have an RSI then please follow the guidance of your doctor.
