I've recently had a large cerebral lupus flare causing a huge amount of seizures and fitting, and after the seizure is over and I've "come round," I have the uncontrollable urge to keep shivering, or shaking, or a movement which may resemble tapping one's foot, or something along those lines. Does anyone else have this side effect? I've recently started on Plaquenil and don't know whether this is causing it. I'm at a loss, because it's putting so much stress on my muscles, having them keep moving, almost as a stimulant. It relaxes me... almost like someone with autism may rock back and forth to calm themselves down?
