Is it normal to burn after Trivagin, lasting several hours?

I used recently for a few days during and after the infection, the gel only worsened the condition, and I did not immediately associate that such severe pain, burning, itching and mucosal rupture is after it. I've never done anything like this before, I even had trouble sleeping. I thought it was another very nasty infection. Over a week I was back to normal, gel to throw away. And let me add that I have never been allergic, but with age something has changed.
