Wisconsin law lets you recover when a crash makes an existing condition worse. The other side takes you as they find you, and they do not get off the hook just because you had a bad back before. What matters right now is proving aggravation: what your back was like before the crash, what changed after, and how your doctors connect that change to the wreck.

If you drive Uber, DoorDash, or Amazon Flex around Appleton, move fast before records, app data, and camera footage disappear.

The most useful proof is:

• Pre-crash records showing your baseline: old MRIs, chiropractor notes, physical therapy, work restrictions, pain levels, and whether you were still driving long shifts
• Post-crash records showing the change: ER visit, urgent care, orthopedic exam, new imaging, stronger meds, missed gigs, lifting limits, numbness, or new leg symptoms
• A doctor's opinion saying the crash aggravated a pre-existing condition, not just "you have degeneration"
• Crash evidence tying force to injury: police report, vehicle photos, dashcam, witness names, and app trip records
• Wage proof from the rideshare or delivery app showing lost income after the crash

Example: a DoorDash driver is rear-ended on I-41 near Appleton during summer tourist traffic. The insurer finds a two-year-old MRI with a bulging disc and says the pain is "pre-existing." But before the wreck, the driver was completing deliveries, lifting orders, and working full days. After the crash, there is a new ER record, a fresh MRI showing worse nerve compression, and a spine doctor notes new radiating leg pain and work limits. That difference is the case.

Get your records from ThedaCare Regional Medical Center-Appleton, urgent care, PT, and any prior treating doctor now. In Wisconsin, the general deadline for most injury claims is 3 years, but evidence gets weaker long before that. Also, Wisconsin has no cap on non-economic damages in most auto injury cases, so pain, loss of function, and flare-ups matter.
