Hello, I am 18. About a week ago, I woke up every hour or two hours. This lasted for 3 days. Also, if I would lay down, I would feel chest pain. But no shortness of breath. I was very worried at that time, because I have mild foot cramps and I already thought it might be ALS at that time. My mom then gave an anti anxiety magnesium pill and I could sleep for 3 night well again, even the chest pain stopped. However the last 2 nights, I woke up like 2-3 times a night and last night like every other hour again. I am afraid it is ALS weakening my breathing muscles. I do a lot of football and weight training and my stamina did not worsen and i dont feel any shortness of breath there, but I read somewhere that sleep problems are the first to come. I do not have any headache, confussion when waking up. Just the regular wakings. I can remember my dreams.
