Thanks RD - just trying to make sense of all the nonsense that is bfs. My arms have changed texture and are much more fatty while my hands and feet are skin, tendons, and bones. No real weakness that I can tell. Middle back pain associated with quivering/trembling-like twitching shortly after lying down and first thing in the morning is my latest thing. We all seem just a bit different and yet the same. Good day to you!
