Pain occurs when the forearm muscles become tight and pull on their attachment to the epicondyle, which is a bony knob at the elbow; the medial epicondyle for the front of the forearm and the lateral epicondyle for the back of the forearm. Activity causes additional pull and continues the pain cycle. Relief is provided by placing a compressive barrier between the muscles and the epicondyle, effectively shifting the pull to the barrier. Taking the stress off the epicondyle helps prevent further injury and pain, and allows for more efficient healing.
