I have Peripheral Nerve Hyperexcitability with a diagnosis of Cramp Fasciculation Syndrome. I also have spinal column and cord issues with stenosis at all levels. I only have stenosis on lumbar spine where nerves exit column. I understand your pain and stiffness and cramping. I don’t understand how the neurologist could give you a peripheral diagnosis without doing an EMG or NCS, that is how they found my peripheral nervous system issues. Hopefully they have put you on medications to help with your symptoms. My primary care doctor was fantastic and used medications I take now long before I had any diagnosis. She treated my symptoms and made me comfortable, I am so thankful for her.
