Classic migraines often cause auras, photophobia, unilateral foci, nausea, and pounding headaches. Botox may reduce the frequency or severity of headaches. Botulinum tox may also be used to treat recurrent tension headaches in the frontal and occipital regions.
If the patient has "trigger points" for her headaches, the site of the trigger area may be injected. The glabella, forehead, lateral brow, temporalis muscle and upper portion of the trapezius muscle as it enters into the occiput are the most common trigger areas. Injection of a trigger area can relieve classic or common migraines and tension headaches.
Topical anesthesia is not necessary in most cases. In addition, Botox injections of the temporalis muscle may be performed.
For the posterior type headaches, trigger points are identified by digital pressure to the back of the neck near the origin of the trapezius muscle. A 1-inch needle is then directed into the muscle through the skin, deep toward the bone, and Botox is injected into the muscle. Typically 5 to 10 BU should be injected into this trigger area and massaged into the muscle after injection.
Some patients experience immediate relief reduces the number of painful days in a percentage of migraine sufferers. Results can last 3 to 6 months and can be profound. In some patients there are no noticeable results.
