Am I suppose to be totally confused???? Different Docs spout different things. I had a very proactive doc, he moved away. New one very cautious, double blind guy. New specialist says this, this and that not true. Other docs say this, this and that very true, be aware. All reputable doctors!!! I am my best advocate, choosing what I believe and do. With MS you get a lot of interaction with doctors, a lot of experience, a lot of confusion. Those who were once like gods (doctors) are just humans you find out. No blind trust anymore.
