It's been 10 days since I got botox on my jaw, and I was happy that my jaw line was smooth, so I massaged it while hoping the swelling would go down. But the next day, my mouth and facial muscles suddenly felt heavy and my jaw started hurting..?ㅜㅜ And when I woke up the next day, my previously thin face had become U-shaped and I had trouble pronouncing words. This must be a side effect, right?
