Okay this will sound ridiculous or and crazy but I gained weight and only in my chin! I am now a skinny woman with a double chin!

How is that possible? What can be done about it?

Gaining weight everywhere else I know how to deal with it but this I am completely baffled and also ashamed.

I was on YouTube before coming here and I found a few videos of chin exercises, in the comments I saw a few people with my problem and a few others says that it actually works but some said that it hurt them.

So anyone here knows good chin exercises? Is there anything that can be done to get rid of fat in chins without surgery?
