Most online calculators assume a straightforward timeline: injury → treatment → stabilization → impairment/rating → resolution. In Illinois, outcomes can shift when there’s any uncertainty around:
- How quickly the injury was reported after a shift change, weekend, or travel day
- Whether symptoms worsened gradually (common with repetitive lifting or cumulative strain)
- Whether your work restrictions match what your doctor actually documented
- Whether the insurer questions causation (for example, when records show gaps or inconsistent descriptions)
A calculator can be a starting point for questions—not a substitute for reviewing your claim file and medical records.
