Colour evolutionErythema appears within minutes, followed by reddish-purple or dark-blue discoloration as blood accumulates. Over 5–10 days the pigment breaks down, passing through blue, green, yellow and finally light-brown before fading .

Clinical findings vary by mechanism (blunt vs. penetrating) and the structures involved, but the following features are characteristic.

In whiplash-associated disorders, discomfort often begins hours after the impact and is accompanied by stiffness.
