After all these years I’ve recently developed a disturbing new symptom, shakiness. It’s beyond nervousness. It seems to rise and fall with mental state - from calmness, light shakiness to agitation, noticeably shaky. It might be more pronounced when tired as in sleep deprived or after light stimulation, e.g. walking or reading. We’re talking about visible sal shaker shaking, to the point of needing to use 2 hands to keep a glass of water still. Is this kind of shakiness part of your CFS? If so, does it just come about periodically or seem to be a ‘stage’ pre- or post- PEM; or a state of mind??
