Masseter Botox

Hi. I was hoping if anyone in the chat could give some insight. So I got masseter Botox yesterday and all throughout the rest of the day I had such a bad headache. It’s the next day now and my jaw area hurts so bad. Like it feels tight sore and achy. The injector said this could happen but I wanted to hear if anyone had some personal experience as well? Cause I’m starting to freak out thinking something is wrong. My whole head feels like it’s being squeezed as well, like pressure. Is this normal? I also got some filler dissolver in my lips as well. Idk how to explain it but it feels like I’m in like an active TMJ flare up. Which is odd because I thought it would do the opposite. Instead it feels like the Botox has made it worse. Will this subside in the next few days? Is it normal to feel some pain? And has anyone else had this experience? I also noticed that it’s a little hard to open my mouth. Like it clicks a lot.. is it just after effects that will eventually subside?
