As a person who has MS, I'm interested in this, but doubtful about it too. There have been so many thoughts and ideas that seem like 'the one', but fail to come through at the end.
I was diagnosed with Relapsing Remitting Multiple Sclerosis, in 2010, and put on one MS medication, which was OK, but not pleasant to inject into my once a week. I was doing better when on this medication, but it isn't a cure and was never thought to be.
I was then put on another medication, tablets this time, and they're working well, or I am anyway, my mobility good, and no relapses!
So medicines can be wonderful, for sure, but not all work for everyone, so testing is vital ...
