I want to get jaw Botox!!

I like dried seafood products, so I tend to eat them often.

My husband and younger brother always tease me about my jaw muscles, saying they're not normal..ㅠㅠ I got hit when I was young, but I didn't feel much effect!!! These days, I get annoyed just hearing my jaw make sounds~~ㅋㅋ If anyone has experienced effects from being hit, please recommend a hospital.
