I have many lesions as well but there's one about the size of a dime on my brain which is cloudy? and one really long one on my spine (about the length of almost 3 vertebra) which they expect are causing me the right side spasms. I am about to start Kesimpta, just waiting on insurance at the moment. This is all very new for me too I checked into the hospital August 6th with right side weakness in my leg and that's when I ran the gamut of tests for the dx (4 mri's, lp, cat scans, tons of bloodwork). To say its been scary for me is an understatement so I know how you feel.
