sorry you are struggling.
Best advice is to go where the big boys are. they can tell a vit def from a lyme symptom and be able to separate it from an MS event. Once you have a diagnosis in hand, you can use the local guy so you dont have to travel all the time, and they are quite capable of doing follow ups. if you run into trouble or the disease goes crazy, you can always go back to see the big boys, but for most things the local guy can speak to the big boys on the phone.
Good luck, let us know.
