I was laying awake last night trying to figure out what could cause the burning feeling... I do think I understand why burning most likely means no NMD... because there are two different types of nerves basically...Afferent Nerves and Efferent NervesNMD's...I assume... are disorders of the efferent nerves, also known as motor neurons.If you're having a burning sensation, then isn't this a completely different nerve in itself? (The Afferent nerve or sensory neurons)Afferent nerves send signals from the muscle to the brain (like a burning sensation), efferent nerves send signals from the brain to the muscle...Again..I'm just guessing...I think too much...but it makes sense to me... maybe BFS involves more than just motor neurons?
