## Short answer

An injury does not have to be visible to matter. Care records can help show the harm and its link to the event.

## Hypothetical example

A person has no cuts after a crash. Later, a doctor finds a concussion.

## How the rule works

A civil claim focuses on proven harm. It is not limited to cuts, bruises, or broken bones. Records about symptoms and care can help explain harm that is not visible.

## What can change the answer

Symptoms alone do not prove who caused them. Past health and other possible causes may need review.

## A useful next step

Get medical care as needed. Describe symptoms honestly and keep dated notes on changes.

## What if I am unsure whether the crash caused an injury?

Seek medical advice for health questions. Symptoms can need evaluation even without a visible mark. A legal claim still needs proof of harm and its cause.

## Court decisions behind this answer

### Capelouto v. Kaiser Foundation Hospitals (1972)

7 Cal.3d 889, pp. 892–895. Pain may be shown by more than a medical bill. The court allowed lay proof and, in some cases, inferences from the injury.

Limit: This does not set a price for pain. You still need proof, and some claims have special limits.

### Mitchell v. Gonzales (1991)

54 Cal.3d 1041, pp. 1049–1053. The court favored a substantial-factor instruction for cause in fact over a confusing older instruction.

Limit: Proof of a careless act alone is not enough. The claimed harm must still be linked to that act.
