First MRI I ever had when I was about 40 showed leasions and MS was suggested. I'm now pretty much bed ridden with the use of a powerchair at 67yo. I have reason to believe the 'Type 7' inoculation when us boys from Phoenix, AZ entered the Army in '69 anticipating going overseas may have had something to do with my MS. I've always gotten alot of natural sunlight vitamin D because I always swam competitively here in Phoenix and still go outside at least 1/2 hour every day and am not vitamin D deficient. The VA wants to blame the environent and get rid of us which isn't happening! I'm contstantly finding other similar stories and will persue this until the end. I'm pretty healthy otherwise so it will be a few years!
