I'd like some advice on MS (Multiple Sclerosis).? My grandmother had it and consequently passed away from it, hers was unfortunately the very advanced kind. My mother was diagnosed at age 35 I believe.. she is 47 now. I have exhibited symptoms, but wonder when is a good time to get tested for it? I am 25. How do they test for it? I've brought it up to my PCP ( Primary Care Provider) but most doctors are hesitant to test for this as I've found, since it is a very tricky disease which is hard to diagnose until it's nearly too late to do any good about it. I've also heard mixed results about whether or not the medical community agrees on if it is hereditary or not. I think my family would be a prime example that it IS possible. If you have this, or have family with it I would love your thoughts and insights and any advice you can shed on the subject. Thank you!
