Lisa,
I was diagnosed with Fibromyalgia more than 9 years ago. Despite treatment, my symptoms never got better. I suffered from wierd vision problems, sore, weak muscles, and shortness of breath. Physical activity made my symptoms worse and I was in constant pain. I had muscle spasms in my legs, arms, even my face. All of these symptoms would come and go. Last month I was diagnosed with a disease called Myasthenia Gravis. It is a highly misdiagnosed autoimmune disease, and most doctors would never think to look for it. Look it up online and see if the symptoms fit. Ask the neuro to test you for this, and other autoimmune diseases. You don't have to suffer with misdiagnosis.
