Not every work injury happens in one accident. Repetitive strain and occupational disease develop over time from repeated movements, awkward positions, vibration, or exposure at work. They can still be covered by Illinois workers’ compensation. This guide is general information only — see the Disclaimer.
Examples
Carpal tunnel from repeated hand use, back or shoulder pain from repeated lifting, hearing loss from noise exposure, and lung or skin conditions from workplace exposures can all be occupational conditions, depending on medical evidence.
Why timing is tricky
There is no single accident date. The date you knew — or should have known — the condition was work-related can affect notice and filing deadlines. Report in writing as soon as you suspect a work connection, and see a doctor who can document the work connection. See How to report in writing.
Pre-existing conditions
A pre-existing condition does not automatically bar a claim. If work aggravated or accelerated a condition, medical evidence about that aggravation matters. Keep records of work tasks, symptoms over time, and treatment, including physical therapy if recommended.
If a claim is denied, see Claim denied and consider Connect with a lawyer.
