Have you looked into Myasthenia Gravis? It has similar symptons. I was diagnosed with it a year ago. Weakness in the extremities, numbness, tingle feeling along with double vision, slurred speech and swallowing problems. You don't have to have all these symptons to have MG. I would have a neuralogist run a special blood test to see. A rare disease so a lot of doctors don't know about it. Good luck in finding out what you have.
