I have it on both my head and spine granted I was told I have a lot of lesions like old ones at the time I was diagnosed and being on the ocrevus has kept me good with nothing new showing up since I started it but I do still have numb feet well my whole leg in general and its mainly my right and but that is good that you are going to have them look at the MRI of your spine to make sure they might even have you get a new one done just to be sure that there isn't anything new or even old just in case they missed anything just because the new MRI is going to be fresh on how your spine looks now more recent, try having your feet elevated sometimes for a few minutes it's not much but it helps a bit with the circulation to get the blood flowing on them, hopefully that helps ☺️and I hope they are able to give you some answers when you go in to get your spine MRI's looked at☺️

Sorry it's a long comment lol😭😅😅😅
