I didn't see your post until now. Sorry I didn't welcome you to Neuro Talk before this. I am sorry for what your son is experiencing. Truly he needs an MRI of his back to make sure no nerves are hitting the spinal cord. I do know the private expense of this as I had no insurance in this country. What you are describing could be so many different things, and we are no doctors here. PN may have some of the symptoms, but I have not heard of the kind of severity in symptoms you are describing. He does have neurological symptoms, the best bet would be to get a good reputable Neurologist for a complete workup. Brain scan too. I am sorry this happened to your son. Let me know how he does. I also know how scarry all this can be for a family. I am here to listen any time you need a friend. ginnie
