They worked tremendously for me! I had them for 5 days (1g IVSM per day) along with Lemtrada. By day 3 my walking was notably better, by day 5 I needed just a cane (not my walker) and I'm still walking unassisted since about 1 week post-infusions. It could be the Lemtrada working now too at one month post, but it's mostly steroids I think.
