"I already had a bad back, so I probably don't have a case." It is one of the most common, and most mistaken, things injured people tell themselves. A prior condition does not disqualify you. Florida law recognizes that an accident can make an existing injury worse, and you can generally recover for that worsening, even if you could not have sued for the underlying condition itself. The catch is that insurers love to blame your history, so understanding how this works matters.
The Rule: You Take the Victim as You Find Them
A long-standing principle, sometimes called the "eggshell plaintiff" rule, holds that a wrongdoer takes the injured person as they find them. If someone's negligence worsens a condition you already had, the fact that you were more vulnerable is not a defense. So a driver who rear-ends you does not escape responsibility simply because your spine already had wear or a prior injury. What you generally recover for is the aggravation, the additional harm the accident caused, on top of where you were before.
What "Aggravation" Actually Means
The claim is not that the accident created a condition from nothing; it is that the accident made an existing one meaningfully worse. That can look like:
- A previously manageable back or neck condition that becomes painful, limiting, or requires new treatment.
- A prior injury that had healed or stabilized being re-injured or destabilized.
- Degenerative changes that were asymptomatic becoming symptomatic after the crash.
The law generally allows recovery for that change, the difference between your condition before and after, even though the underlying vulnerability existed first.

How Insurers Use Your History Against You
This is precisely where insurers focus. Expect them to pull your prior medical records and argue that your pain is "just" your preexisting condition or "degenerative," not the crash. They may point to old imaging, past complaints, or earlier treatment to suggest nothing changed. That argument is often overstated, but it is effective when a claimant is unprepared for it. Answering it is a central part of a well-handled aggravation claim.
Why Documentation Is Everything Here
Because the case turns on the difference between "before" and "after," the record is what wins it. Helpful documentation includes:
- Your baseline, what your condition and function were like before the crash.
- Prompt post-crash care that ties the change to the accident.
- Clear descriptions to providers of what is new or worse since the crash.
- Comparative findings, such as imaging or evaluations that show a change.
- Honest, consistent history; hiding a prior condition backfires, while disclosing it lets it be addressed head-on.
Be Upfront About Your History
It can be tempting to downplay a prior injury, but that is the wrong move. If an insurer or defense later discovers an undisclosed condition, it damages your credibility and hands them exactly the argument they wanted. The stronger approach is to be transparent, and then show, with the records, how the accident changed things. A preexisting condition handled openly is very different from one that looks hidden.
What to Do If You Have a Preexisting Condition
- Get prompt medical care and describe how your symptoms changed after the crash.
- Tell providers about your prior condition; accuracy protects your claim.
- Keep your records, both before and after, so the change is documented.
- Do not give a recorded statement to the insurer about your history before getting advice.
- Do not assume you have no case just because you were not perfectly healthy.
- Talk to a personal injury attorney who can frame the aggravation properly.
