Hi, it is really hurt, and the pain you never felt before. I got stung also early this year. and i put my hand directly into very hot water, and tied my elbow. so the pain did not travel to other place. and is better go see doctor.i did not see doctor, actually the pain goes off after 2-3 hours, may be because i dip inside hot water for 30 minutes.
I hope you recover well, be more careful in future. ;-)
