I had no idea BFS could cause cramping. My twitching is mostly in the right leg still but it is appearing in the other leg frequently alongside areas in my torso like my abdomen and back somewhat frequently. My biggest concern isn’t even the twitching now it is the minor ache my right leg is feeling and bottom of foot pain/ache. I am hoping this does subside, just hard not knowing for sure. Thank you for replying as that does make me feel better there is another diagnosis this could be. I know ALS does not cause tingling or numbness and I’ve felt that on the occasion so I’m holding on that for hope.
