Trigeminal neuralgia or TN causes sudden facial pain that feels like a burn or shock. The classic, Type 1 form is sporadic and can last a few seconds to a couple of minutes. Multiple attacks may take place over a couple of hours. A patient with Type 2 TN may have constant pain; some patients have both forms. Also called tic douloureux, TN is a neuropathic pain, associated with nerve injury or lesion. It’s associated with the trigeminal nerve, one of a dozen nerve pairs linked to the brain. TN may be caused by a blood vessel pressing on this nerve and damaging the myelin sheath that protects it. Other, rare causes include a tumor, a malformation of arteries and veins, disease such as multiple sclerosis, or injury.
Headaches come in a variety of forms, from debilitating chronic migraines to nagging tension headaches to cervicogenic headaches originating in the neck. Headaches can interfere with daily life and work, but there are several treatment options. Nearly half of adults have had a headache in the last year, according to estimates.
