7 months after masseter botox, right side feels numb. Should I be concerned? What can be causing this?

I have TMJ and doctors told me to get masseter botox. I had it done twice in a year with almost 6 months apart. I kind of regret it my face really slimmed down and I feel like there is asymmetry in my face. Also, I don't know why but I have a weird feeling on my right side, it doesn't seem like there is a difference but my mimics are feeling different and also my eyesight feels different. It has been 7 months since my last botox. I also massaged it after a couple of months
