mmclane--I am so sorry for your daughter's situation. Altho she apparently does not have an actual "diagnosis" of multiple sclerosis, the doctor seems to be operating under the same principles (and offering the same treatments) that most of us have seen (starting with steroids and moving on to even bigger guns!).

My concern is with your comment,

is the one with the expertise and medical knowledge.
I would ask, in the case of each of the five drug treatments, "What is each supposed to target and do, if you don't know what you are dealing with.
My prayers are with you.
