You have come to the right place. Information is Power.
Consider B-12 - Jimmylegs knows this stuff.
Consider Curcumin and Ascorbic Acid - see my posts in the natural approach.
If you genuinly think you are Secondary Progressive, push the doctor about the issue of when you were relapse remitting. Secondary means, your current condition was preceded by a slightly different sort of condition. Consider internet searching on the the combo treatment of copaxone/novantrone. There is a 5 year study you will want to read.
read my 101 then 102 post. Knowledge is power. Don't be a guinea pig and just follow what the Doc says, get info and ask questions. You can still follow what the doc says, but then it's not a blind trust.
If you are not yet in a wheel chair, but sinking fast, PUSH the novantrone question and PUSH HARD, relentlessly.
Find your local MS society. Go to an event and network. This is a good way to get a lot of info about Doctor's in your area. Folks will tell you who they have left and who they are with now. Socialize your way to knowledge. You can't beat this thing with brute force, it's impossible. Get positive, consider prayer, hang out here and read. good luck, napay
