Off With My Head! It Just Causes Me Pain! In Full Flare: a post by Finding Out Fibro on Occipital Migraines and Trigeminal Neuralgia, fibromyalgia flare ups, and persevering through untreated chronic pain that is often severe enough to cause suicidal thoughts.
Trigeminal neuralgia- "The cause of this disease is not currently known, but it may have to do with blood vessels putting pressure on the trigeminal nerve as it leaves the brain stem. The vessels pressure on the nerve may cause the myelin sheath to deteriorate, which would affect the nerve’s ability to generate action potentials and may lead to the facial pain... A person suffering from Type 1 trigeminal neuralgia often experiences sharp facial pain half of their day."
Trigeminal neuralgia is marked by intense bolts of pain, usually around the face. - See more at: http://www.timescolonist.com/life/rare-nerve-disorder-causes-severe-facial-pain-1.635544#sthash.ICgI9PKE.dpuf
