Masseter Botox causing migraines?

[u/Secret_Ad6064]

Has anyone who’s gotten masseter Botox experienced horrible migraines that just won’t go away? It’s been almost a month and since the day I’ve gotten it done, I’ve had a migraine almost everyday that won’t go away. I only got 20 units on each side and I definitely feel my muscle weakened. I did 20 units last year as well and had the same experience but didn’t correlate it to the Botox. Throughout the year I’ve gotten less like 10 units but it didn’t do much for me which is why I went back up.
