RSI Warning Signs: A Self-Check for Anyone Who Types All Day

Most people who develop a serious repetitive strain injury knew something was wrong six to eighteen months before they did anything about it. The early signs are easy to dismiss because they go away. A wrist ache after a long day. A finger that tingles for ten seconds and then doesn't. A morning where your grip feels weak when you pick up your coffee mug, but is fine by lunch. The symptoms cycle in and out, which is exactly why people ignore them until they don't cycle out anymore.

This guide is a practical self-check. It will not diagnose you — only a doctor can do that. What it will do is help you locate yourself on the four-stage progression of typing-related RSI, and tell you what the right intervention is at each stage. The goal is to catch this early, when the cost of fixing it is small.

What "RSI" Actually Means

"Repetitive strain injury" is an umbrella term, not a single condition. When typing causes problems, it is usually one (or several) of these:

• Carpal tunnel syndrome — compression of the median nerve at the wrist, causing tingling and numbness in the thumb, index, middle, and half of the ring finger. The most well-known typing injury.
• Cubital tunnel syndrome — compression of the ulnar nerve at the elbow, causing symptoms in the ring and pinky fingers. Common in people who keep their elbows bent for long periods.
• Tendinitis — inflammation of tendons in the wrist, forearm, or fingers. Usually feels like a dull ache that gets worse with use.
• De Quervain's tenosynovitis — inflammation of the tendons on the thumb side of the wrist. Aggravated by phone scrolling and mouse use.
• Forearm myofascial pain — chronic muscle tightness and trigger points from sustained gripping and typing posture. Often the underlying driver of the others.

You do not need to know which one you have to act on the early signs. The interventions for stage 1 and 2 are the same regardless of the specific diagnosis: reduce volume, fix posture, restore movement.

The Four Stages

RSI progresses in fairly predictable stages. The earlier you intervene, the lower the cost. The chart below is a simplified version of what occupational health clinicians use.

The boundary that matters most is between stages 1 and 2. Stage 1 reliably resolves with behavior change. Stage 2 has a meaningful chance of becoming permanent if you do not intervene aggressively.

The Self-Check

Read each item carefully. "Sometimes" means once a month or so. "Often" means more than once a week. Be honest — most people who later regret ignoring symptoms answered "sometimes" for months before it was "often."

How to Score Yourself

• 0–2 boxes checked, all "sometimes": Likely Stage 1 or pre-stage. Take the warning seriously now, before it progresses. The interventions are easy at this stage.
• 3–6 boxes, mostly "sometimes": Stage 1 to 2. Aggressive ergonomics changes and a doctor visit for a baseline are warranted.
• 3+ boxes "often", especially in the numbness or weakness sections: Stage 2 or 3. See a doctor this month. Do not wait.
• Sleep disturbance, dropping objects, or constant symptoms: Stage 3 or 4. See a hand specialist now. This level of dysfunction does not resolve on its own.

A Quick Test for Carpal Tunnel: The Phalen Maneuver

If you suspect carpal tunnel specifically, you can do a rough self-test that doctors use as a quick screening:

1. Hold both hands in front of you, palms facing you.
2. Bend your wrists down so the backs of your hands press against each other (fingers pointing down).
3. Hold that position for 60 seconds.

If during that minute you feel tingling, numbness, or pain in the thumb, index, middle, or ring fingers — that is a positive Phalen sign. It is not diagnostic on its own, but it is the most consistent self-test for carpal tunnel and is reason enough to see a doctor for a real evaluation.

What Actually Helps (In Order of Importance)

1. Reduce typing volume

This is the single biggest lever, and the one most people skip because it feels impossible. It is not impossible, but it requires changing how you work, not just how you sit. The two practical ways to dramatically cut typing volume without cutting output are:

• Dictation for communication. Slack, email, notes, comments — anywhere you are typing prose. Modern dictation tools have crossed the accuracy threshold where this is genuinely faster, not just easier.
• Templating, snippets, and shortcuts. If you type the same things repeatedly, automate them with TextExpander, snippets, or Raycast.

Reducing daily keystroke count by 40% is a realistic target. Many people with stage 1–2 RSI report symptoms substantially improving within 2–4 weeks of cutting volume by half.

2. Fix the obvious ergonomics

• Wrists straight, not bent. Use a wrist rest only as a place to rest between keystrokes, not while typing.
• Forearms parallel to the floor. Adjust chair height; the keyboard should be at or just below elbow level.
• Screen at eye level. If you are looking down, your shoulders are rolling forward and your forearms are angling up.
• Negative-tilt or split keyboard if you have early symptoms. A traditional QWERTY keyboard with the back legs popped up forces ulnar deviation. Either flatten it (or tilt it negatively) or get a split design.

3. Take micro-breaks, not long ones

The research is clear: 30 seconds of movement every 30 minutes prevents more harm than 15 minutes off every two hours. Set a timer. Stand up, shake out your hands, look at something far away. The break is not for your eyes. It is for the static load on your forearm muscles.

4. See a physical therapist before a surgeon

If you are at Stage 2 or higher, a hand or occupational therapist can do more for you in six visits than a year of "trying to be more careful" will. They will give you the specific stretches, the exact strengthening sequence, and the soft-tissue work that addresses your individual pattern. Most major insurers cover this. Most people do not seek it out until they have already lost six months to symptoms they could have stopped.

Why Dictation Specifically

I want to be honest about why dictation comes up in an RSI article: it is the only typing-volume reduction strategy that scales. Better posture is helpful, but you can have perfect posture and still type 6 hours a day, and 6 hours of perfect-posture typing is still 6 hours of repetitive load on the same tendons.

Dictation moves a chunk of that load off your hands entirely. The realistic split for most knowledge workers is something like 60% dictation (Slack, email, drafts, notes) and 40% typing (code, editing, navigation, anything that needs precision). That cuts your daily keystroke count roughly in half — which is exactly the volume reduction that turns Stage 2 symptoms back into Stage 1 over a month or two.

Voice Keyboard Pro is the dictation tool we built. The reason it shows up in this article is that we get a steady stream of email from people who say some version of "my hands started hurting and I needed to stop typing — what now?" Dictation is one of the few answers that actually works at scale, and we wanted to make a tool that did it well enough that the answer was easy.

Hold a hotkey, speak, release — text appears at your cursor in any app. There is no separate window to switch to, no transcription queue. The workflow matters because if dictation adds friction, you will go back to typing the moment you are tired. Friction-free dictation is the only kind that becomes a habit.

The best time to address RSI is before you have it. The second best time is now, while it is still reversible.

What Not to Do

• Do not just buy a wrist brace and keep typing. Wrist braces help during sleep (to prevent unconscious wrist flexion) but typing in a brace masks the symptoms while the underlying damage continues. Use a brace at night, not at the keyboard.
• Do not power through. The "warrior" approach to RSI — taking ibuprofen and pushing through — is exactly how stage 2 becomes stage 4. Pain is information. Listen to it.
• Do not assume cracking and popping is the issue. Joint cracking is mostly harmless. Pain, tingling, numbness, and weakness are the signals that matter. Crepitus (joint noise) without pain is usually fine.
• Do not switch to a "fancier" mouse and call it solved. Vertical mice and trackballs help, but they are a 10% solution to a 100% problem. The volume of input is the issue, not just the input device.

The Bottom Line

RSI from typing is one of the few major health risks of knowledge work that is genuinely preventable, and one of the few that we know exactly how to prevent. The interventions are not glamorous: reduce volume, fix posture, take breaks, get help early. Almost no one does them until they have to.

If you checked any of the boxes above, the cost of acting now is a few weeks of behavior change. The cost of waiting until you cannot type without pain is a year or more of recovery, and possibly permanent dysfunction. The math is not subtle.
