Welcome to my world of "Limboland".
I have almost the same identical symptoms as you, except I have intermittent R eye blurriness too. I only have 1 attack and 2 lesions.
I went to 2 neuros myself and the last one said something about the lesions are not perpendicular to the ventricle (Huh?)
Most days, I feel OK and on a pain scale of 1-10, my symptoms are in the 3-5 range. So, I am no longer "desperate" to get a dx.
Many people on this board were able to get a lumbar puncture (only after insisting on one to the doctor) and this is how they were able to come up with a 2nd clinical diagnostic conclusion that they had MS. You may want to go back to one of the neuro's and insist that they do a lumbar puncture.
However, I am surprised that your 2nd MRI was not considered another clinical tool to meet the McDonald Criteria of "dissemination in time" if more lesions appeared.
Best wishes to you
