Hi Sarah, Yes I get those also. It almost feels like I got mexican jumping beans in my muscles. It will last for a few days and then go away as quickly as it comes. I'm not sure if it's Lupus related or not. Some times I think it is caused by my meds but since I take the same meds all the time it'skind of hard to figure out why it would come and go like it does. I know this question has been asked before so hopfully others will come up with their info on it.
