Botox in masseter 14 months ago under hospital dr for tmj, a days later I had a giant bruise and then my face dropped as if I had a stroke on one side, thought Botox either injected into a nerve branch or spread- seemed to be risorius and zygomaticus major affected. It’s bb but I'm still having trouble with muscles not working and often getting facial cramps and other muscles overcompensating -it’s been over a year and now I just looks like i need a face lift and muscles still don’t fully work.
