After getting square jaw botox

I had a jaw sound from my jaw and got a square jaw boss on June 3rd. It was my first time getting it.

I thought it was just sore. A few days passed.

I'm busy so I'm just asking now

One side of my face is swollen and sore and I keep getting headaches.

They say it'll be okay after 2~7 days, but I still have jaw sounds, stiffness, swelling that hasn't gone down, and a headache. Are these side effects?

When will the swelling go back?
