I am a 25 year male I have muscle wasting in left hand and the nerves can be seen. I can't lift heavy objects and drop them eventually. I can't even hang with my left hand. I had undergone MRI and nerve conduction test. The doctor (neurologist) said I have monomelic amyotrophy but no one in my family has this except my elder brother but his hand is not weak as mine and he also don't have that much wasting. Please help I think I am going to lose the ability to work with left hand. Sometimes my hand freezes and I cant even bend my fingers. I don't have any wasting in other parts of the body.
