If you already have a back injury, knee problem, or chronic medical condition before your crash, you might worry that you can’t file a claim. Insurance companies can count on that fear. They often argue that your pain was “already there” to avoid paying what you deserve.
But Pennsylvania law protects you. If a car accident made your pre-existing condition worse, you may still be entitled to full compensation. Working with an experienced car accident attorney can help injured clients every day whose existing injuries were aggravated by someone else’s negligence.
You Can Recover Compensation When an Accident Makes an Existing Injury Worse
Many people assume a prior injury automatically disqualifies them from filing a personal injury claim. That’s not the truth.
Pennsylvania follows what’s known as the “eggshell plaintiff” rule. This legal doctrine says an at-fault driver must take you as you are. If you’re more vulnerable because of a past injury or medical condition, they are still responsible for the harm they cause, even if someone else might have been less seriously hurt.
If their negligence made your condition worse, even if someone without your medical history would have suffered less severe injuries, they’re still responsible for the worsening conditions that their actions caused.
What Does “Aggravation of a Pre-Existing Condition” Mean?
In personal injury law, aggravation means more than a temporary flare-up. It refers to a measurable worsening of your condition caused by the accident.
This might include:
- New structural damage on imaging (MRI, CT, X-ray)
- Surgery or injections you didn’t previously need
- Increased pain or reduced mobility
- Permanent loss of function
- Faster progression of a degenerative condition
The key question is simple: Did the crash create new problems or significantly worsen your baseline health? If the answer is yes, you likely have a claim.
Examples of Car Accidents That Aggravate Existing Injuries
Real-life cases often look like this:
- A driver with manageable back pain suffers a herniated disc after a rear-end collision and needs surgery.
- A marathon runner who had recovered from knee surgery experienced complete ligament failure after a crash with a drunk driver.
- An older adult with a concussion history developed persistent post-concussion syndrome after another driver ran a red light.
How We Build a Pre-Existing Injury Car Accident Claim in PA
To recover compensation after a car accident, you’ll need to prove three things:
- That the other driver was negligent
- That the accident directly caused your condition to worsen
- That the aggravation corresponds to specific damages
The process of proving these three points should start immediately after your accident and continue through investigation, treatment, and negotiation.
What to Do Immediately After the Accident
Your actions early on can make a big difference.
- Get medical care within 24-48 hours
- Tell your doctor about both the accident and your prior condition
- Follow all treatment recommendations
- Avoid recorded statements to insurance adjusters before speaking with a lawyer
Prompt care creates documentation that protects your claim.
Medical Records Matter Most
To prove your aggravated injury claim in Pennsylvania, you’ll need pre-accident records showing your condition’s baseline and post-accident documentation demonstrating measurable changes.
Comparative imaging is especially powerful for this purpose. An MRI showing a bulging disc before and a herniated disc afterward would be strong proof of an aggravated injury.
Make sure you gather documentation showing all escalated treatment from over-the-counter medication to injections and surgery. Our team works directly with medical providers to gather and organize this documentation for you.
Medical Experts Can Explain Causation
Insurance companies often try to argue that your worsened condition resulted from natural progression rather than accident trauma.
Medical experts can push back. They review your history and explain, in clear, understandable terms, how trauma from the crash caused your specific aggravation. That testimony can be critical in negotiations or at trial.
Challenges You May Face With a Pre-Existing Injury Claim
Insurance companies look for any reason to minimize payouts. When they see a pre-existing condition, they often try to shift blame. Here’s what to expect.
They’ll Use Your Medical History Against You
Adjusters will request extensive medical records to identify prior complaints. This allows them to argue that your symptoms existed before the accident. They may even hire defense experts to minimize the accident’s role.
Their goal is to get you to accept a low settlement offer, often claiming responsibility for only temporary aggravation. Without the benefit of strong legal representation, many victims accept woefully inadequate settlements.
They’ll Look for Gaps in Treatment
Proving aggravation means providing objective medical evidence, not just complaints of feeling worse. If there are gaps in your treatment, insurance companies may try to argue that your worsening condition is unrelated to the accident.
Being consistent in your post-accident treatment allows you to retain credibility and avoid discrepancies between your story and the evidence.
They May Delay Until the Deadline Passes
There are strict timelines related to personal injury claims. Pennsylvania gives you two years from your accident to file a lawsuit.
Two years may sound like plenty of time, but building a strong case requires months of treatment to establish aggravation. Don’t wait to contact a lawyer and begin filing your claim. The longer you wait, the harder it will be to achieve fair compensation.
They’ll Try to Pay Only “Part” of Your Damages
Insurance companies often attempt to “apportion” damages, arguing that they’re only responsible for a certain percentage of your injuries.
Don’t accept a partial payout. An experienced attorney can help you demonstrate that the accident caused distinct, measurable worsening requiring full compensation.
FAQs About Car Accidents and Pre-Existing Conditions
Can I still recover compensation if I had back problems before my accident?
Yes. If the crash made your back condition worse, you can seek damages for that aggravation. You’re not barred from recovery simply because you had prior issues.
What if I was already receiving treatment?
Ongoing care can actually help your case. Ongoing treatment creates a medical history and can help establish a baseline for your condition. Your medical records may help to prove how the accident aggravated your injury.
How do I prove the accident made my condition worse and not just natural aging?
You’ll need medical evidence to prove your case. This can include pre- and post-accident imaging, treatment records, physician notes, and medical expert testimony. An experienced attorney can help you collect and present relevant evidence.
Does the insurance company get all my medical records?
Insurance companies must request medical authorizations; you’re not required to provide unlimited access. You can work with an attorney to negotiate relevant releases while protecting your medical privacy. If you’re in doubt, contact an attorney before signing releases.
What if my old injury was from a previous car accident?
The source of your old injury is legally irrelevant. The only important issue is whether or not your injury got worse after your most recent accident.
Can I claim damages if the accident required surgery I was avoiding?
Yes. If you managed your condition without surgery before the accident, but surgery was required after it, this may help demonstrate a worsening condition. If you can, contact an experienced attorney before undergoing surgery to cover your bases.
Do I really need a lawyer for a pre-existing injury claim?
In most cases, yes. These claims are more complex, and insurers aggressively dispute them. Legal representation significantly improves your chances of full compensation.
How does a personal injury attorney help with aggravated injury claims?
Make sure you find a car accident lawyer experienced with old injuries. They will help you collect relevant evidence, negotiate with insurance adjusters, and prepare for trial if needed. Strong legal representation is essential for maximizing recovery.
