The type of MS your doctor dx you with matters because some insurance carriers will not approve DMD's for those dx'ed with SPMS or PPMS. Some only approve meds for RRMS.

I'm not sure how long you've been on C but I've read that it takes up to a year to see any recognizable benefits from it. And even that time frame I'm not sure of.

I don't know how you can tell what type you have.....it seems to me like it's a hindsight thing. Looking back over your sx and trying to decipher which ones remit and which ones just continue to get progressively worse. It's hard to tell sometimes.

I'm thinking I probably have progressed to SPMS but I haven't been formally dx'ed with that type yet.
