There is no difinitive test for MS. It is a process of ilimination. My doctor told me i didn't have MS after i had an MRI even after the doctor who reviwed my MRI listed possible MS as my diagnosis and said i should have further testing. my doctor said it was the stress of my hectic schedule and i needed to find a way to cope with the stress.
I went to a neurologist who only deals with MS patients, he performed a spinal tap and reviewed my MRIs, he diagnosed ne with MS. You should discuss your symptoms with a neurologist who specializes in the area of MS. Your neighborhood neurologist may not know what he is dealing with. This was my situation after i pushed my doctor for a referral to my 1st neurologist. He told me i was young and healthy and MS was not possible. What an idiot he is. YOU HAVE TO FIND A NEUROLOGIST WHO SPECIALIZES IN MS.
i wish you well.
