I have been waking up in the morning with my hands painful & in a fist; I can open them, but cannot fold them again properly. it is like the movement of a robot, my fingers bend once then again to touch my palm. it is not a smooth movement. this lasts for about ten minutes, then they are numb throughout the day (the numbness is not unusual) . I have severe neuropathic pain from a disease called syringomyelia. I am not certain if the hand cramping is related to the disease. my fingers feel warm/hot under cold water. I have weakness and pain in my left arm and recently, my left leg. I have pain/ weakness on my right side occasionally. I am concerned about my hands, and what this means and what it could be. please, please tell me if this is a symptom of als. I have become progressively worse over the last six months and don't know what is happening to me. thank you.
