Migraine and vascular headaches are caused by the dilation, distention, and inflammation of the branches of the carotid artery. They are often throbbing headaches affecting the areas behind the eyes. They may be accompanied by nausea or vomiting, moodiness, depression, irritability, and visual disturbances. They may also be caused by eating or inhaling toxic or irritating substances.
Cluster headaches come suddenly, are severe but of short duration, and tend to recur several times in a day. They usually affect only one side of the head near the eyes, but may radiate to the temple, nose, jaw, and neck. They can cause reddening of the eyes, tearing and nasal stuffiness. They may be caused by allergies or chemical sensitivities and temporary relief can often be achieved using antihistamines.
Tension headaches are usually caused by tension or spasms in the muscles of the neck and shoulders. They are an occupational hazard of desk-bound employees, dentists, chiropractors, carpenters, and others forced to remain in awkward positions for long intervals.
Migraine, vascular, and tension headaches usually respond well to CMO because of the chronic inflammatory processes involved. Cluster headaches that are normally relived by antihistamines often respond even better when CMO is added to the therapy. CMO may even help reduce the number of recurrences per day.
