Pre-Existing Injuries and Your Texas Personal Injury Claim
Prior conditions can create medical-causation questions in an injury claim. A claimed aggravation requires evidence distinguishing the pre-event condition from any post-event change, and recoverable damages depend on the applicable facts and law. This guide explains documentation considerations. For city-specific resources, see our Texas accident guides. For a broad educational range, use the calculator.

The eggshell plaintiff rule in Texas
Texas follows the "eggshell plaintiff" rule: the defendant takes the victim as they find them. If a crash aggravates a pre-existing condition — even one that made you more susceptible to injury than a healthy person — the at-fault party is liable for the full extent of the worsening. You don't recover less simply because you had a prior condition. The rule protects accident victims with old injuries, degenerative disc disease, prior surgeries, or chronic pain from being unfairly denied compensation.
Aggravation vs. causation — what you must prove
You don't have to prove the crash caused your original condition. You only have to prove the crash made it worse. That means showing a difference between your baseline (how you felt before the crash) and your condition after. Medical testimony and records comparing the pre- and post-collision condition may be relevant to aggravation, including clinical findings, imaging where appropriate, symptoms, treatment history and a qualified causation opinion.
How pre-existing conditions may affect claim evaluation
Prior imaging, prior symptoms, treatment history and post-event changes may all be relevant to medical causation. Evidence of the person's baseline condition and documented post-event findings can help an individualized causation analysis, but no single comparison automatically resolves the issue.
The evidence that defeats the pre-existing defense
Potentially relevant evidence may include pre-event medical records, symptom history, comparison imaging when medically appropriate, treating-provider opinions and a timeline of reported changes. The significance of each source depends on the medical and factual context; no single category is automatically the strongest evidence.
What to do if you had a prior injury
First, don't hide it — disclose the prior condition to your doctor and lawyer. Hiding a pre-existing injury is the single fastest way to lose a claim. Second, get a thorough exam right after the crash so your doctor can document what's new. Third, follow your treatment plan consistently. Finally, estimate your case worth so you understand the value of the aggravation claim before you negotiate.

Frequently asked questions
Can I still file a claim if I had a prior injury?
Yes. Texas law lets you recover for the aggravation of a pre-existing condition caused by a crash. You must prove the crash made the condition worse, not that it caused the original condition. Estimate your claim to see what the aggravation is worth.
What is the eggshell plaintiff rule?
It means the at-fault party is liable for the full extent of the harm they cause, even if a pre-existing condition made you more susceptible to injury than a healthy person. You don't recover less for being vulnerable.
Will an old MRI hurt my case?
Not if the crash made things worse. Prior imaging may help provide a pre-event comparison when clinically and factually relevant. Differences between studies must be interpreted with the medical history and other evidence and do not independently establish traumatic aggravation.
How much can I recover if the crash aggravated a pre-existing condition?
You recover for the full extent of the worsening — the additional medical bills, lost income, and pain and suffering caused by the aggravation. The amount depends on how much worse the condition became. Use our free calculator for a broad educational preliminary range.
