What is Delayed Symptoms?

Injuries or medical symptoms that do not manifest immediately at the time of an accident but appear days, weeks, or even months later.

Understanding Delayed Symptoms

Delayed symptoms are common in motor vehicle collisions and other traumatic events due to adrenaline, inflammation that develops gradually, and the body's initial shock response. Common delayed symptoms include headaches, back pain, neck stiffness, numbness, and cognitive difficulties. Seeking prompt medical attention after any accident is critical, even if you feel fine, to document a baseline and establish a connection between the accident and later symptoms.
