After boric acid burning

So I had bv that was very stubborn and wouldn’t go away for two months. I had three rounds of oral antibiotics and one round of internal antibiotics, then 21 days boric acid, but I missed a day and had extreme burning when I missed it, I thought taking it would make me feel better but the burning only got worse. My doctor told me to stop taking the boric acid after that. It’s been three days since I stopped the boric acid and my vagina has been burning. The burning started immediately after missing the dose and hasn’t gone away. Is this normal while my vagina recovers? Or is this just a sign that the BV is still there?
