Whiplash Headache
Headache after whiplash injury often shows itself for the first time on the morning after the accident. The pain sweeps up from the neck and over the back of the head. Most sufferers find that heat on the back of the neck will ease the headache. Cold makes it worse.
Neck movements often aggravate the problem – particularly if the neck is moved towards extension: looking up to the ceiling is often very painful.
