Welcome to NT, Margo...lots of support, info and laughs here!!
I was dxd in 2008, but had symptoms many years before. I had a negative lumbar puncture, but lesions. It wasn't until a year after that mri that I got the dx due to symptoms.
I'm RRMS, but the stupid symptoms just keep rolling in...
I would also suggest an MS specialist. My first neuro thought I had migraines causing symptoms (not); the second opinion thought it was from my fibro

the third neuro I saw dxd me, but then gave me over to his nurse practitioner, who took her time calling back (sometimes a week or more), and always pooh-poohed my symptom reports.
My current neuro concentrates on MS; he is very conservative with meds and with IV steroid use, and monitors me well. I am very happy with his care.
Good luck, and keep us up to date on what is going on with you; do research, and make sure you keep a symptom journal with dates so you can bring that to your doc's appt.
