Headaches can be caused by many different conditions or injuries, some of which are very serious. If you have nausea, blurred or double vision or vomiting that accompany your headache, you may need to present to the nearest emergency room.
Conversely, many headaches can be caused underlying neck conditions, including: whiplash, sprain/strains and disc damage. In that case, managing the symptoms of the headache will be temporary. You will need to treat the neck or cervical condition to prevent future headaches and manage your wellness.
Auto accidents with soft tissue injuries often cause headaches. Most often, treatment of the underlying condition help patients with their headaches.
