Patients will be randomized into 2 intervention groups. One will receive the FMT from month 1 and for the first 6 months (early intervention group). On the other hand, the other group will be a control group during the first 6 months and will receive the FMT for the last 6 months of the study. Patients will be screened for eligibility based on MS diagnosis and EDSS and if eligible then consented. All qualified patients will not be currently or recently treated with high dose steroids.
