Boric acid caused skin irritation?

Two days ago I started taking boric acid suppositories and my vagina started to itch and burn and I stopped taking it and things are starting to go back to normal and I was wondering if this has happened to anyone else? I’m starting to get some bumps down there but I also just shaved and the last time I got an std test I was clean and have only done anything with one other person since then and he says he’s clean too so I’m hoping this was just all from the suppositories...?
