MS is about therories, there isn't alot known about this disease. Everything about this disease is a guessing game. The majority of meds prescribed for MS are used "off label."
Some wonder why I don't believe in the DMDs. How is it possible to have medications slow a disease down or help when the disease is not understood?
Then you have to figure in each persons reaction to medications. What a medication is prescribed for and how well it works or doesn't work depends on the patients reaction as well as the disease.
Doctors don't understand the disease, researchers don't understand the disease and patients are left confused, angry and without answers...makes perfect sense
