The FDA has approved Copaxane a MS disease modifying drug (DMD)to be used in persons who have suffered a CIS, Clinically Isolated Syndrome. It sounds as if you qualify and perhaps starting a DMD might to be your advantage.
Talk to your MS neurologist about this. It could prevent any further relapses. I had only 2 lesions on my MRI and ZERO O-bands and still got a diagnosis.
To the left of this column is a list of Health Pages, most written by one of our members, Quix, a retired pediatrician with MS. They are factual and based on sound scientific evidence.
Here is the link to the one about having MS with no lesions, there are many more that may be helpful to you:

Please let us know if we can be of more help to you.
Best,
