I hope you get this. I just read your post, and you just listed every symptom that me and 3,000 other people have suffered from, and we all have what is called BFS. Your story matches mine almost to a 'T", even the smaller left calf and unbalanced feeling while walking, swallowing problems and all. Please send me a message if you would like more information, but I highly recommend you google Benign Fasiculation Syndrome, and look for a site called AboutBFS.com. I think you would be very surprised at how similar your story and symptoms are to ours. Take care. Please dont worry about ALS
