I've endured migraines for nearly fifty years and in that time have noticed that they change roughly every seven years or so. They'll change in strength, or frequency, or symptoms, or whatever.
The most recent change, which began about three years ago, is akin to a mild seizure. When the pain gets really bad and I'm bedridden, my body writhes uncontrollably and continues to do so until I'm thoroughly exhausted. If I'm seated, then one leg starts to bounce. If I try to stop it, one arm and hand begins to shake and contort. The more I try to hold it in, the more violently the shaking takes hold.
I've had an MRI and it's normal. And it doesn't seem to be related to the medication because I've been on a variety of meds over the years. Even after the migraine has run its course, I remain jittery.
Is anyone else experiencing this or have any clue as to what might be causing it?
