Burning feet

Past two weeks or so my feet feel like they are burning. It gets so much worse when I’m back home after working for 10 hours. This is a new symptom for me and I’ve recently switched to Briumvi from Ocrevus. I was on ocrevus since 2019 and I was very stable, some flaring of old symptoms but never anything new. Im going to email my nurses but it’s just frustrating after being so stable for 7 years 🙃
