It sounds like you could be experiencing fasciculations, which are a kind of muscle twitch or spasm you can actually see under the skin. They can hurt, and look really frightening - they often happen in the calf of the leg, the hands, and the eyelids. There are many different factors that can trigger them, including several medications, electrolyte imbalances, vitamin deficiencies, and other medical conditions. So that could be part of what's happening. Although it can be neurological, it doesn't sound like your neurologist has been very helpful in the past, so you might have better luck talking to your other docs. You might want to look at the meds you are taking to see if this is listed as a side effect for any of them.
