Symptoms may develop gradually, become more noticeable during ordinary activity, or be difficult to recognize immediately after a collision. The fact that a person did not report pain or other symptoms at the scene does not necessarily establish that no injury occurred. Medical sources recognize that symptoms associated with some trauma-related conditions might not begin immediately. That does not mean, though, that every later symptom was caused by the collision. A healthcare professional must evaluate the person’s condition, consider possible causes, and recommend appropriate care.
Avoid trying to diagnose the problem yourself or assuming that the crash caused every symptom that appears afterward. Instead, record when the symptoms began, how they changed, and whether particular activities made them more noticeable. Provide that information accurately to the healthcare professional performing the evaluation.
Statements made immediately after the crash can also become relevant. If you told another driver, an officer, or an insurance representative that you felt fine, the insurer may compare that statement with later medical records. An early statement is part of the evidence, but it does not automatically decide whether a later-reported condition was related to the collision.
