I had my gallbladder out last year... They said it was like a bag of marbles ready to bust. My pregnancy in 2009 caused cholestasis, where your bile becomes sludge and your liver leaks bile into your blood stream. From 2009 until last year I suffered horrible gall attacks, but never once felt any type of movement... Just that feeling of ny torso being on fire and nausea. So it has to be something else you have going on. I know as a child I would have movement and twitching in my legs which I now know was restless leg.. But there is no such thing as restless abs lol Damn though... Anything involving the liver is scary. I hope you can figure it out!
