Which is harder to bear, bone-pounding pain or the sensation of being shocked by heat?

For some time now, every time I look in the mirror, I see my cheeks sagging, so I've been debating a hundred times whether or not to book an InMode appointment.

I looked up reviews and saw some saying that it feels like your skin is burning because the tip gets incredibly hot when it touches you during the procedure, rather than just being painful. That really scared me. I heard some people suffered from blisters on their faces or burn marks, so is it really just a matter of luck? They say they check the temperature on the machine screen while going in, but I'm terrified that if the doctor just pushes it in carelessly, something really bad could happen.

I've heard the pain itself feels completely different from a sharp sting. Between the bone-hitting pain and the intense burning sensation, which is harder to bear? I'm wondering if it's tolerable.
