What is Tennis Elbow?

Tennis Elbow is a frequent cause of elbow and arm pain for computer users. The pain comes from the tendon which connects to the boney bit on the outside of the elbow. Sometimes pain is also felt in the muscle on the outer side of the forearm.

Muscles and tendons get damaged when they are held in a tense position for too long or over stretched.

Tennis Elbow symptoms are easily diagnosed by your Doctor, perhaps with X-ray or ultra-sound being used to aid diagnosis. Golfers Elbow and Tennis Elbow are almost mirror conditions of each other. See Golfer’s Elbow

What causes Tennis Elbow

Computer users sadly are today’s tennis elbow sufferers and it is rarely caused by smashing a tennis ball hard with a backhand stroke!

Traditionally, causes were such as tightening a screw with your arm extended, shoveling snow, chopping wood, gardening, walking excited dogs on leashes etc. All scenarios where the arm was tense and extended for a while. Now, computer use is a significant cause!

For Computer users, an ergonomic vertical mouse is the best means of avoiding further computer mouse or laptop touchpad strain and as a preventative solution. Evoluent is the best, in our opinion, and our recommendation. Perixx and Anker are good however and at only a fifth of the price are well worth trying on a tight budget.

Vertical mice look strange but are surprisingly easy to get used to after 20 minutes or so and most sufferers feel relief immediately.
