With Volneumer, are you more concerned about the sensation of heat than the pain during the procedure?

While researching Volneumer, I saw a lot of talk about its effectiveness and duration, but I became more curious about what it actually feels like during the procedure.

Since everyone describes it differently—whether it feels like a stinging sensation or a strong burning sensation—I couldn't really get a sense of how intense it was.

I tend to be sensitive to pain, so I get nervous for no reason even before the procedure.

For those who actually received it, was it bearable?
