Hi Connie, my name is Sandy and my hubby has ms. There are many test that are done to rule out ms. MRI, LP, EEG, blood work, etc.. My suggestion for you is to go over to our ms forum and look around and ask whatever you need to. Some people go years before being diagnosed and then some get a diagnosis quickly.
My advice is to not research too much because your doctor isn't sure about what's going on. Write down all your symptoms and any questions you have for the neuro before you go. Include when these symptoms started and how they affect you, what helps, etc..
