<s>[INST] What are the main symptoms for MS? I was diagnosed with Fibromyalgia, but I don t think that is all that is going on. Some things I have read say that you can have white spots on the brain which I have and when I have issues it seems to be more in my upper arm muscles and then spasms in my legs and feet. Could this be MS? [/INST] I am sorry about your troubles. However what do you mean by having spots in your brain, have you had a CT OR MRI? The only way of visualising MS brain lesions is through MRI. As for the physical signs what you mention could be caused by fibromyalgia. Not that I can exclude MS, it's a disease with many ways of presentation according to the affected areas, but it's a diagnosis which is suspected by a careful neurological exam and history taking and confirmed by MRI. </s>
