Yes, legions can present over time...and go away, and new ones form, and its a never ending, changing battle with legions....each time a new one presents, new symtoms usually present, which is why both relapses and progression take place.
MS is not contagious, nor is it USUALLY Genetic. THere is less than 3% chance of your mother and you having it....however, it can happen. I dont know anyone it happened to, but I have read the stats...

8 legions is NOTHING. I had over 50 at the time of dx, and I actually got my dx in less than a month....the LP is what secured it for me...that, and the symtoms which put me in the ER, and then got me to a Neuro. (tingling, burinng, dizziness, numbness).

Your absolutely right to be telling yourself you would rather have MS than a terminal disease, you dont die from MS, you die with it!
Try to relax.....chances are, you dont have MS, however, there may be some chance you have another neurological or even auto-immune issue. There is proof that auto-immune diseases do run genetically in famililes. For instance, my mother has PMR, which is alot like Rheumatoid Athritis, and my father, has Parkinsons....now, I have MS. No one in our family was ever sick until 2005, when my dad got Parkinsons really fast, and it has progressed really badly. Mom got sick next and about 14 months later I started with symtoms....anything IS possible, but 2 people with MS, although possible, is highly improbably statistically...
Keep us posted.
