How Pre-Existing Conditions Can Affect Your Personal Injury Claim

When someone suffers an accident, insurance companies and defense attorneys often look for ways to reduce the value of a personal injury claim. One of the most common tactics is pointing to pre-existing conditions, health issues, or injuries that existed before the accident.

At Duncan Injury Group, we’ve seen insurers argue that new pain and suffering are simply “old problems” resurfacing. The truth is more complex: under Florida law, victims are entitled to compensation when an accident worsens or aggravates a pre-existing condition. Knowing how to prove this difference can make or break a case.

Understanding Pre-Existing Conditions in Injury Claims

A pre-existing condition may include:

  • Prior back or neck injuries
  • Degenerative disc disease or arthritis
  • Previous surgeries or fractures
  • Chronic pain conditions (fibromyalgia, migraines, etc.)
  • Mental health issues such as PTSD or depression

These conditions don’t eliminate your right to compensation. Instead, the legal issue is whether the accident made the condition worse, legally called aggravation of a pre-existing condition.

Why Insurance Companies Focus on Pre-Existing Conditions

Insurance companies use pre-existing conditions to:

  1. Deny Causation – Claim the accident didn’t cause the injury at all.
  2. Reduce Value – Argue that damages should be lower because the injury existed before.
  3. Shift Blame – Suggest the victim’s lifestyle or health, not the defendant’s negligence, caused the current problems.

This is especially common in Florida car accidents, slip and fall cases, and workplace injuries where soft-tissue damage or spinal issues are involved.

Florida Law: The “Eggshell Plaintiff” Doctrine

Florida follows what’s known as the Eggshell Plaintiff Rule. This means a negligent party is responsible for all injuries their actions cause, even if the victim was more vulnerable due to a prior condition.

In other words, if you had a weak back and a crash made it much worse, the defendant can’t escape liability just because you weren’t in perfect health before.

Strategies for Protecting Your Claim

At Duncan Injury Group, we use proven strategies to overcome insurance tactics:

  • Gather Complete Medical Records – Showing your health before and after the accident creates a timeline that proves aggravation.
  • Use Expert Testimony – Doctors can explain how trauma worsened a condition, even if you already had symptoms.
  • Highlight Daily Impact – Journals, witness statements, and job restrictions show how your life changed after the accident.
  • Challenge Insurance Bias – We push back when insurers attempt to “cherry-pick” old records to downplay injuries.

Common Examples in Cases

  • Car Accidents: A driver with prior whiplash suffers new herniated discs after a collision on a highway.
  • Slip & Falls: A person with arthritis falls at a grocery store, leading to accelerated joint deterioration.
  • Workplace Accidents: An employee with an old knee injury now requires surgery after a construction site fall.

In each case, the new trauma significantly worsened an old condition, and the law supports compensation.

Steps to Take If You Have a Pre-Existing Condition

If you’re injured in and have a prior medical history:

  1. Seek Immediate Medical Care – Tell your doctor about both old and new symptoms.
  2. Be Honest – Never hide a prior condition. Concealment can damage credibility.

  3. Preserve Records – Keep copies of MRIs, X-rays, and doctors’ notes.

  4. Avoid Insurance Statements – Insurers may twist your words to claim everything was pre-existing.

  5. Call an Experienced Attorney – Only skilled lawyers know how to frame aggravation of conditions under Florida law.

FAQs About Pre-Existing Conditions and Injury Claims

Does having a pre-existing condition hurt my case?
Not necessarily. You can still recover compensation if the accident made the condition worse.

Will the insurance company get all my medical history?
They can request records, but your lawyer can limit access to only what’s relevant.

What if my old injury was already healed?
If new trauma re-injured or aggravated the area, you are entitled to damages.

Can I get compensation for pain and suffering?
Yes. Florida law allows recovery for increased pain, emotional trauma, and reduced quality of life.

How long do I have to file a claim in Florida?
Most personal injury cases have a two-year statute of limitations (as of 2023 changes). Missing the deadline can bar your claim.

Every state has deadlines for filing a claim. Waiting too long can mean losing your right to recover damages.
