Hi, about one year ago, I was operated on for the second time for a bulging disc (L5-S1). Three months after the surgery, my calf muscles commenced fasciculating. This worsened up to a point where now I have to sleep with a brace in order not to wake up in terror due to extreme muscle cramp in my calf. A specialist diagnised this as BFS (Bening Fasciculation Syndrome) but I doubt this since sometimes it s better or worse depending on how much sleep I had etc... Could this be the result of scartissue irritating the nerve at the L5-S1 position?

Summarized question: What causes Benign fasciculation syndrome?
