Ocrevus subcut vs infusion etc

Hi all, I’ve been on Ocrevus for almost 6 years now, it’s been great fir my disease progression etc. However my last treatment about 5 months ago, I received the subcut instead of infusion. And tbh I’ve feel like I’ve just never bounced back from the pre treatment crap gap. I wanted to go back on the infusion but my hospital won’t be offering it anymore, and my only infusion option is Birumvi (I think that’s what it’s called). I’m reluctant to switch from Ocrevus when it’s worked so we’ll disease wise, but I feel so shitty all the time. Does anyone have any thoughts on this?
