I had to see a neurologist a month ago as well and had to have a brain MRI done. My symptoms were tingling in the feet, vision problems and memory/concentration issues. My brain MRI came back clear for MS. So I am guessing it is all down to fibro. I was not very happy with the neurologist to be honest, he told me if the MRI scan came back clear, I should see a psychiatrist - without even asking me whether I was already seeing one or not. (I've suffered from serious mental health issues my whole life)
So your symptoms could be MS, they could also be something else, but they could just as well be a part of fibro. Just take it step by step, find a doctor that you can communicate well with. Having a doctor you feel comfortable with is so important. Stay strong, stay positive.
