4Jcobb I have the same thing for 6 months now. My spine is really define on my back , my chest has gone flat, my arms got thinner and soft , I have a indent on the top of my head and one on the upper left of my forehead , my calf muscles are barely there , and my rib cage now sticks out under my chest . I only lost 10 pounds going from 175 to 165 I consider that a big drop for me considering I dont weight that much. I also twitch all over from my stomach to my butt to my leg ... basically all over 24/7 all types of twitching too. Its like the the worst thing because it reminds you , you have something wrong with you 24/7. I have trouble doing basic activities meaning Bowling and Golfing my hobbies . Meaning i can do them without a problem but i might suffer from a few pulled muscles and a upset nerve somewhere. It makes me cut off must physical activities i love to do. People say that it cant be atrophy if you dont loose strength so I test my strength with weights. Its below my average but my strength isn't totally diminished. Im pretty young so I dont believe its ALS but the possibility of it can get to me sometimes. Im going for a EMG monday to see if my muscles are clean but if you figure out what you have I would very interested in knowing .
