what is called mouse elbow is actually not a new disease. it is a variant of a well known RSI disease called epicondylitis. Pretty much the same condition as golf elbow Medial Epicondylitis, but in case of mouse elbow the condition is affecting selected finger muscles/tendons which are the only one that produce pain. Often it is a single finger tendon/muscle combination -- index finger. This is especially typical for gamers, who are using programmable mouse like Logitech G600 with multiple buttons.
Medial epicondylitis, is caused by damage from overuse to the muscles and tendons that control your wrist and fingers. The damage is typically related to excess or repeated stress — especially finger motions. Improper posture, bad equipment, as well as too little warm-up or poor conditioning, also can contribute tot he development of the disease. Absence of wrist support on the mousepad and palm support on the keyboard (as well as wrong inline of the keyboard (it should be negative with F-keys lower then the blank key, like in Microsoft Natural Ergonomic Keyboard 4000) is pretty common and can be another contributing factor
In case you condition is connected with keyboard abuse (too much repetitive input of sequences like Ctrl-C), you more often get a variation of tennis elbow (lateral epicondyle.) which has more difficult to treat.Epicondylitis is a type of musculoskeletal disorder that refers to an inflammation of an epicondyle. Types include:
The easiest test is to try to lift you desk with one of your finders. Some fingers, usually index finger which is the most overworked finger, might feel pain. that's typical symptom of mouse elbow. You can also get it of your left hand with the excessive number of Ctrl-C Ctrl-V combinations while typing.
The fact that you need to make many small and very precise movements of the mouse for 4 hours or more (with often the break for lunch only) eventfully tend to destroy the heath of your arm. Especially if you use mouse for 12 or more hours in total, like many programmers do. Type of disease you get many vary, but in essence you get what you deserve -- human hand is not designed for such a load. Contributing factors are (see also Preventing RSI) :
Judging from forums I read this affect women more frequently then men.
One important fact is that you almost should rest on some kind of foam to absorb excessive stress more readily and you wrist should not be elevated to hold the mouse. Those two inch foam sheets that is sold for bed cover can be adapted for other uses as they are often oversized and can be striped to make length or width fit the size of your bed :-).
If index finger tendons are the one that suffers from RSI you can try offload some load by using middle finger instead (G600 has second buttin that is conviviniet for such purpose). brace in this case will not help, but elastic sleeve can.
For some vertical mouse might provide some level of relief, at least psychological, but your mileage may vary. Cheap model to try if it helps might be
FotoFo and Sharkk mice are of adequate quality and is less then $10 on Amazon.
Despite the fact that using your mouse is by no means a strenuous activity, overtime the forearm extensor muscles in your forearm become fatigued and start to wear down.
This causes your muscles to contract and constrict resulting in a tight feeling in your forearms and pain at the attachment point on your elbow where your forearm muscles attach.
You start to experience pain in the muscles around your elbow which can sometimes cause pain further down your forearm and into your wrist and hand.

Over the last few weeks, I’ve felt a nagging and persistent pain in my elbow, right between those two little bones on the underside (if you hold your arm slightly bent).
... A classic case of strain caused by overwork, it can develop in three ways:
- Muscle pain: If you have a dull ache up and down the arm from the hand to the elbow, that’s your muscles talking to you.
- Tendon pain: If you’re feeling more of a sharp, searing pain centered at the back of the elbow, that’s your tendons.
- A combination of both: Got the dull ache and the sharp pain? Lucky you—both your muscles and tendons are involved.
“Chronic exhaustion” is a good term for what’s happening here. We use the muscles and tendons over and over again, tensing them consistently without relaxing them often enough. The result is a repetitive stress injury. We experience inflammation in the muscles, and possibly in the tendons as well (though there is some medical debate about whether tendons actually become inflamed). There may be tiny tears in the fibers of both.What to Do First
In most cases, the problem occurs because we’re typing with poor form. That’s good news, because it means we can make some adjustments to prevent the injury from happening again.
If you’re already suffering, though, you have to heal first. Here are some tips to help you do that more quickly:
How to Prevent Computer Elbow
- Rest: Your body needs time to heal. This can be a tough one, though, particularly if you write (or work at the computer) for a living. Do your best. Try to cut back on your typing time at least for a little while. Give your tissues a chance to recover.
- Stretch: Computer elbow is the result of tensing the muscles and tendons too long without release. They become tight and shortened, so stretching will help relieve the pain. Start slow. Massage therapist Paul Ingraham suggests this one: Extend your arm out in front of you and press the back of your hand against the wall with the fingers pointed out to the side. Straighten your elbow and press into the wall so you’re really flexing your wrist. Hold for one minute. Just stretching your wrist back and forth will also help. There are some other great stretches here.
- Ice it: Ice can help tame muscle inflammation, and can also stimulate the tissue to encourage healing. Ice as many times as you like as long as it seems to be helping.
- Alternate hot and cold: This helps stimulate circulation, and getting increased blood flow to the injury encourages healing. Ice for five to ten minutes, and then rotate with a heating pad or hot water bottle.
- Try a self massage: Some great tips here.
- Watch how you sleep: Sleeping on the affected arm or elbow can pinch the nerves and slow healing.
Next, it’s time to make some changes. Keep in mind that if you continue to work the same way, you may end up with a chronic condition that gets steadily worse—eventually causing more pain, tingling, and numbness. Severe cases can interfere with your job or your daily writing goals.
- Don’t raise the back of your keyboard: This actually forces the wrists to work in a “cocked” position that increases strain. You want your hands and arms to be in a straight line. Consider lowering the back of the keyboard instead. If you can’t adjust it this way, try raising your chair a bit, or add something underneath the front of the keyboard to make it level.
- Use a wrist pad. You want your hands to be level with the keyboard. If they’re not, use a wrist pad to make it so. I’m checking into some for my laptop computer as well—like the Intelligel wrist rest, the Grafiti Palm Pads (for Macs).
- Check your mouse: Make sure your mouse is close by and easy to use. If it’s too high or too far away, you’re extending the forearm too much (over and over again throughout the day), increasing risk of injury. Also, make sure the mouse fits your hand. If it’s too small, you’re finger, hand and wrist muscles will have to remain in a tense position to operate it. You want your hand to be as relaxed as possible. I use a tracking ball mouse and have found it to be the most comfortable of any I’ve tried. (My elbow pain is in my left arm, not the right, so the mouse is working well!)
- Relax your shoulders: Do you ever notice that your shoulders are up around your ears while you’re working? Remind yourself to relax. Muscle tension in the shoulders can radiate down into the arms.
- Keep your desk clear: Clutter causes you to reach and extend more often. You want a clear space between your keyboard, mouse, and working area to minimize muscle work. Remember that the problem here is “repetitive”—the more you lift, extend, tighten, etc., the more likely you are to suffer pain.
- Stretch your fingers: Constantly curled fingers cause writer’s elbow. Stop every thirty minutes and stretch them back toward you. Get up and walk around with your hands down to allow the blood to flow into them.
- Maintain 90 degrees: This is the magic angle. Your forearms should form a 90-degee angle with your upper arm. If you find your forearms are too low or (worse) too high, adjust your chair and keyboard to fix it.
- Fingers in line with forearm. This is one of my problems with my current work setup. My fingers tend to be higher than my wrists and arms. Bad idea. Use a rolled up towel or other cushion to keep your fingers in line with the backs of your hands and your arms—close to how they are when you’re playing the piano, for instance.
- Get a split keyboard: These help your hands stay in a more natural line. I have one on my desktop computer, but of course my laptop, which I use just as much, doesn’t come with this convenience. I wish it did! I have found that propping my wrists up a bit so that they can move with my fingers has helped, though. (See wrist pads above.) Resting my wrists on the computer actually makes the pain worse because my fingers are held up and must move without the help of my arms—resulting in strain.
- Strengthen the muscles: Increasing muscle strength can help prevent the injury from recurring in the future. Do this only after the pain has subsided, though, as otherwise it could worsen the injury. Try squeezing a tennis ball 25 times, or make a fist with your hand and then bend your wrist forward and back using only your hand.
