Month 4 of Kesimpta and herpes flares

Treatment

Hello all đź‘‹
I contracted herpes in my 20s and had about 4 flare ups in my life
Since starting Kesimpta - I took the jab on Sunday night - 4 days ago and feel so ill and laid up, and am now having a herpes flare up too.
I’m wondering if anyone else has this with K and am also looking for reassurance that’s it’s not going to “take me out” each month - as I was feeling so good pre jab.

Thanks in advance xxxx
