Everyone says a bad old MRI means your case is dead, but actually no - Wisconsin law lets you recover when a crash aggravates a pre-existing condition, even if your spine was already a mess before the wreck.

The better question is: can you prove what changed after this crash?

That is where insurers in Kenosha and up the I-94 corridor make their move. They do not just say "you were hurt before." They say your current pain, missed DoorDash or Uber driving time, and treatment were all coming anyway. Same old playbook, different adjuster.

Wisconsin follows the eggshell plaintiff rule. A careless driver takes you as they find you. If a summer tourist slammed into you near Kenosha, or a heat-related tire blowout caused the wreck, the defense does not get a discount because your back was vulnerable.

What matters is evidence showing the crash made things worse:

• before-and-after symptoms
• new imaging or clinical findings
• ER and follow-up records tied closely to the crash date
• a doctor's opinion that the collision caused an aggravation, not just "ongoing degeneration"

If the crash involved a pothole or road condition on a state trunk highway, remember WisDOT controls more than 12,000 miles of those roads, and claims involving government entities can trigger much shorter notice deadlines than the usual injury case timeline.

For most Wisconsin negligence cases, the general lawsuit deadline is 3 years. But with a pre-existing back problem, waiting is especially costly because gaps in treatment let the insurer argue nothing new happened.

So no, old back problems do not kill the claim. The real fight is proving the difference between your baseline and your aggravation.
