I want to wear an off-shoulder top, but does trapezius Botox hurt a lot? Haha.

I want to wear off-shoulder tops with nice necklines when the weather gets warmer, but my shoulders are totally loaded with Pacific Ocean trapezius muscles, so I look way too bulky ㅠㅠ. No matter how much I scrub them with a foam roller, they absolutely won't go down, so I'm debating whether to go to Maypure and get some trapezius Botox to really loosen up. Since they inject my shoulders multiple times, I expect it to be really sore and painful, but is it tolerable even for a scaredy-cat like me? Please leave some genuine reviews from those who have gotten trapezius Botox, such as when my shoulders will drop to a square shape, and whether I should lift heavy things, etc. ㅠㅠ!
