If you spend most of your workday at a computer, you may notice soreness or aching in your wrist, hand, elbow, shoulder, or neck. While sitting at a desk may not seem physically demanding, repetitive movements like typing, clicking, and using a mouse can place stress on muscles and tendons over time.

The good news? Small changes to your workspace and daily routine can help prevent tendinitis from computer use and reduce the risk of it becoming a chronic problem.

What Causes Tendinitis From Computer Use?

Tendinitis occurs when a tendon—the tissue connecting a muscle to a bone—becomes irritated, often from repetitive stress or overuse.

When you work at a computer for hours, you may perform the same movements hundreds or thousands of times a day. Repeated typing, clicking, gripping a mouse, or keeping your wrist in an awkward position can contribute to irritation.

Poor posture and a workstation that isn’t properly adjusted can also increase stress on your muscles and joints.

Common symptoms may include:

• Aching or tenderness around a joint
• Pain with repetitive movements
• Stiffness
• Swelling
• Weakness or reduced grip strength
• Pain that gets worse during or after computer work

How to Prevent Tendinitis When Working at a Computer

1. Adjust Your Workstation

Your computer setup can make a big difference. Keep your monitor at approximately eye level and position your keyboard and mouse so your elbows can remain comfortably close to your body.

Try to keep your wrists in a neutral position rather than constantly bent upward or downward.

2. Use a Laptop Riser and External Keyboard

If you work primarily on a laptop, consider using a laptop riser or stand to bring the screen closer to eye level. This can help reduce the tendency to bend your neck and shoulders forward while working.

However, once your laptop is elevated, the built-in keyboard may be too high for comfortable typing. Pair the laptop stand with an external keyboard and mouse so you can position your hands and arms more comfortably.

Ideally:

• Keep the top of your screen around eye level or slightly below.
• Keep your keyboard and mouse close enough that your elbows can stay comfortably near your sides.
• Keep your wrists in a neutral position, rather than bent upward or downward.
• Keep your shoulders relaxed instead of reaching forward toward your keyboard or mouse.

These simple adjustments can be especially helpful if you spend many hours a day working on a laptop.

3. Take Regular Movement Breaks

One of the easiest ways to reduce repetitive strain is to avoid staying in the same position for hours.

Every 30–60 minutes, take a short break to:

• Stand up and walk around
• Shake out your hands
• Move your wrists and elbows
• Roll your shoulders
• Change positions

Even brief movement breaks can help reduce the amount of repetitive stress placed on your body.

4. Don’t Rely on Your Hands and Wrists Alone

Your entire upper body contributes to computer work. Keep your shoulders relaxed and avoid reaching forward for your mouse or keyboard.

A well-positioned chair and desk can help you maintain better alignment throughout the day.

5. Strengthen Your Muscles

Strong, well-conditioned muscles can better tolerate everyday activities. Depending on your needs, exercises for your forearms, wrists, shoulders, upper back, and core may help improve strength and endurance.

The key is to choose exercises that match your current ability and don’t increase your symptoms.

What If You Already Have Tendinitis?

If you are already experiencing pain, don’t simply push through it and hope it goes away.

Start by identifying what activities are aggravating your symptoms. Reducing repetitive movements, modifying your workstation, and taking more frequent movement breaks may help decrease irritation.

Depending on the location and severity of your symptoms, a physical therapist may recommend:

• Specific stretching and mobility exercises
• Progressive strengthening
• Manual therapy
• Ergonomic modifications
• Activity and workload modifications
• Other treatments to help manage pain and inflammation

The goal isn’t simply to make the pain disappear. A good treatment plan should address why the tendon became irritated in the first place and use physical therapy rehabilitation to gradually rebuild your strength and tolerance for daily activities.
