David...
Welcome to the site. Sorry your doc gave you so little to go on. There are many things to consider. First of all, gwa is probably right and you need to find a more proactive neuro. Your doctor should have an opinion on which meds will be best for you. That's why they get the diplomas on the wall!
Do you know if you have a progressive form of MS or relapsing/remitting MS? Did you have a lumbar puncture? Do you have many lesions shown on MRI? Where are they located? How much disability do you have? Have you been tested for Lyme, a viral infection, Hughes syndrome, nutritional deficits? These are just a few of the questions which can assist your doc in making a diagnosis and choosing a disease modifying program. AND, you should have the answers to all these questions. As a patient, it is up to your doctor to do all the tests and inform you...not the other way around.
As an example, my husband had a positive LP for RRMS, positive MRI, and presented with first flare at age 44. Due to his presentation and limited damage from the disease after steroids, his neuro suggested copaxone, since men in his category had done well in clinical trials. She also suggested diet, nutritional supplements and exercise. She had many medically based opinions...
As I write this, I'm getting infuriated
Good luck, David...I'd really suggest searching your area for a more "opinionated" neuro.
best,
AC
