A relatively common injury to the forearm and elbow region is an overuse of the extensor or flexor tendons of the forearm.
These injuries are commonly known as Tennis Elbow when occurring on the lateral (outside) aspect, and Golfers Elbow when occurring on the medial (inside) aspect. The correct term, epicondylitis, defines inflammation of the bone where the tendon inserts in the elbow region, but new research has suggested that rather than inflammation this may be a reaction to overload. Tennis Elbow is about 5 times more common than Golfers Elbow.
Both are repetitive strain injuries, meaning they occur largely as the result of repetitive overuse, typically due to repetitive movements (Hence the names as both tennis and golf can cause these injuries through the actions involved).
These injuries present as acute pain and tenderness over the bony points on the inside or outside of the elbow, which is generally aggravated by using the muscles of the forearm. Lifting overhand will use the extensor muscles which will be painful in Tennis Elbow, and lifting underhand will use the flexor muscles which will be painful in Golfers Elbow.
While most cases of epicondylitis are self-limiting and will recover within 1 year, there are some therapies that may assist this process.Most importantly, one should protect the area from further injury and prevent aggravation by ceasing the offending activity. If this is not entirely possible then bracing and taping can help by alleviating some of the demand on the involved tissue. I find dry needling to be helpful in many cases, and sometimes the correction of abnormal elbow biomechanics can help further to decrease unnecessary strain on the tendons.
