Forearm pain when typing: what to try first

Cut the number of keystrokes first, by dictating drafts instead of typing them. Then fix arm support and desk height. Forearm pain during typing tracks typing volume and workstation setup together, and volume is the part you can change today.

Not medical advice. If you have numbness, weakness, night pain, or persistent/worsening symptoms, seek medical advice.

1) Reduce typing load (the highest leverage)

• Use dictation for first drafts (emails, docs, notes).
• Edit with the keyboard (precision), but avoid typing every sentence from scratch.
• Start with built-in macOS Dictation: speech to text on Mac.
• If you dictate daily, use a consistent hold-to-dictate hotkey: voice typing for Mac.

2) Fix the basics (support + height)

• Keep keyboard close so you’re not reaching (shoulders relaxed).
• Avoid hard desk edges pressing into your forearms or wrists.
• Consider forearm/upper-extremity support if you tend to hover your arms for long sessions.
• If you use a mouse a lot, try reducing grip/strain (trackpad/trackball) and keep it close to the keyboard.

For deeper ergonomics and posture ideas (plus research context), see: ergonomic split keyboard (evidence + tradeoffs).

3) Try microbreaks, knowing the evidence is weak

• Every 20 minutes: 30 to 60 seconds.
• Once per hour: 3 to 5 minutes (stand up, reset posture).
• The current Cochrane review of extra work breaks reports a pooled standardised mean difference of -0.08, 95% CI -0.35 to 0.18, across three studies and 225 participants, and concludes the evidence is very uncertain (Luger et al., Cochrane 2025, CD012886.pub3). Breaks are cheap and low risk, but do not expect research to back them. Longer version: microbreaks for typing.

If you need a simple plan (7 days)

1. Switch one writing task per day to dictation (e.g., your longest email).
2. Fix your desk edge / arm support so you’re not pressing into hard surfaces.
3. Add microbreaks for one focused work block (start small).
4. If symptoms persist or worsen, get clinical guidance.
