A pre-existing condition injury claim can still be valid when a Florida accident makes an old injury, disease, or physical limitation worse. The important question is usually not whether you had a condition before the incident. It is whether the new event aggravated that condition or created additional symptoms, limitations, or medical needs. Insurance companies often examine earlier medical records closely. That makes clear documentation and honest communication especially important. The following points explain how a pre-existing condition may affect an injury claim and what you can do to preserve useful evidence. 1. A pre-existing condition does not automatically defeat your claim Many people have prior back pain, arthritis, old sports injuries, or degenerative changes before a crash or fall. An at-fault party generally does not get a free pass merely because the injured person was not in perfect health. Florida’s civil jury instructions recognize claims involving the aggravation of an existing disease or physical defect. The recoverable harm, however, must be connected to the aggravation caused by the new incident. That distinction is central to a pre-existing condition injury claim. You are not claiming that the accident created your entire medical history. You are identifying the meaningful difference between your condition before and after the event. 2. The “before and after” comparison matters A useful claim tells a clear, fact-based story. Before the accident, could you work a full shift, exercise, sleep through the night, drive comfortably, or care for your family? Afterward, did the same condition become more painful, frequent, or limiting? Did you need new medication, injections, therapy, imaging, or surgery? Medical records can help show that change, but ordinary life evidence matters too. Employment records, calendars, photographs, messages, and testimony from [...]
