A software developer reported a significant decline in repetitive strain injury symptoms after incorporating large language models into daily work routines. The individual described years of chronic arm pain from typing, including burning sensations and tenderness that required medical attention and lifestyle adjustments such as ergonomic keyboards and frequent breaks. Pain levels fluctuated based on typing patterns, with severe discomfort occurring during extended sessions involving complex key combinations and modifier use. Hand size limitations further complicated keyboard use, particularly when reaching for distant keys.

Beginning in 2026, the developer observed a shift in workflow. Instead of prolonged manual coding sessions requiring hours of continuous typing, tasks increasingly involved prompting language models to generate code drafts followed by brief manual refinement. This change reduced overall keyboard interaction time and shifted focus toward writing and reviewing design specifications. The developer noted improved productivity and fewer instances of acute pain, though fatigue remained. While expressing mixed feelings about AI adoption, they acknowledged that reduced physical strain from typing may have contributed to better musculoskeletal health. The account highlights how automation tools can alter work patterns and potentially mitigate occupational health risks associated with prolonged computer use.
