You see my story on your other thread.

IVSM is meant to stop inflamation and thus end your flare, before any or much permanent nerve damage is done and supposedly There are no inflamations/flares with SPMS

So, with the exception of RPMS-remittive progressive MS, where you still have inflamation, IVSM does little more than a placibo.

If you and your Doc think you are having inflamation, then try ivsm, it may work for you and I hope it does.
