Oh my goodness. That sounds even worse than what my mum did. She tried to inhale with hot salt water and dropped the bowl with the hot water on her lap. Her legs were burnt. I was in a complete shock. I was little at that time and did not know what to do. She let cold water run over it. Your area is much more sensisitive. Ouch!
I hope you get well looked after and heal very soon.
E-hugs from me, too.
