The Early Signs of RSI and How to Change Course Before It's Too Late

Most people who develop repetitive strain injuries do not notice the beginning. There is no single moment, no obvious injury, no incident to point to. There is just a gradual accumulation of small stresses on tendons and nerves until one day the soreness does not go away overnight, and then it does not go away over a weekend, and then you are Googling carpal tunnel at 11pm and feeling quietly alarmed.

The early signs are easy to dismiss. That is the problem.

What Early RSI Actually Feels Like

The first symptoms are not usually pain. They are more subtle than that. A faint ache in the forearms after a long session. Stiffness in the fingers in the morning that clears up once you start moving. Occasional tingling or numbness in the ring finger and pinky, which are served by the ulnar nerve. A sense of fatigue in the hands that arrives earlier in the day than it used to.

None of these feel like emergencies. All of them are signals worth taking seriously.

If you type more than four hours a day, and most knowledge workers do, you are in a risk category whether or not you feel symptoms right now.

What Actually Causes It

Repetitive strain injuries are cumulative. The tendons and sheaths in your hands and wrists are not built for thousands of small identical movements performed daily, year after year, with insufficient recovery time.

The position of your wrists matters too. Typing with wrists bent, either up, down, or sideways, creates friction in the carpal tunnel with every keystroke. Tension in your shoulders and neck changes how force is transmitted through your arms. Most people type in a posture they have never consciously chosen, and it is rarely optimal.

Changes That Make a Measurable Difference

Adjusting your setup is not complicated, but it requires intention. Your keyboard should be low enough that your elbows are at roughly 90 degrees and your wrists are flat, not angled upward. A wrist rest sounds helpful but is often counterproductive during actual typing; it is for breaks, not for use while your fingers are moving.

Take breaks that involve actually putting your hands down. Not switching from keyboard to mouse, not picking up your phone. Rest your hands flat on your desk for two minutes every 45 minutes. Set a timer if you need to.

Strength and flexibility help. Simple exercises, like slowly spreading your fingers as wide as possible and holding for five seconds, or making a fist and releasing, maintain tissue health in a way that rest alone does not.

Reducing the Load

The most direct intervention is typing less. This sounds obvious and impractical until you start looking at where your keystrokes actually go.

A significant portion of daily typing, email, Slack, notes, documentation, first drafts, is prose rather than code or structured data. Prose can be dictated. A tool like VoiceInk lets you speak into any Mac application, which means you can offload substantial typing volume to your voice without changing your software environment or your workflow in any major way.

This is not about eliminating typing. It is about reducing cumulative daily load. Dropping from six hours of typing to four hours, by dictating emails and messages and rough drafts, is the kind of change that prevents the problem from developing in the first place.

If You Already Have Symptoms

See a doctor or physiotherapist before self-treating. Carpal tunnel syndrome and other RSI conditions are diagnosable and treatable, but the right treatment depends on what you actually have. Some conditions respond to rest and stretching; others need different interventions.

What does not help is ignoring it and hoping it resolves on its own while maintaining the same workload that caused it.

The Window to Act

The best time to take RSI seriously is before it becomes a problem. If your hands feel fine today, that is an asset worth protecting. Small changes now, posture, breaks, reduced typing volume, add up over years.

Your hands have a lot of work left to do. Treat them accordingly.
