I had 25 units of dysport injected into my masster muscle 10 days ago and today I woke up and cant smile on left side of my n face. I also feel numbness all along the left side of my face. will this get any worse? Is there a chance this will effect my smile permanently? Also is it normal that my face hurts and gets tired when talking?

Abnormal smile after masseter injection will resolve to normal after 3-4 months
There is no need to worry about anything being permanent. This looks like the depressor labia inferioris on the right is affected. I don't know why that muscle would be because it's far away from the masseter. The usually erant muscle affected is the risorius muscle which is just in front of the masseter but this causes a different smile issue with inablility to pull the corner of the mouth wide. Everything should get better with time and there's not much which can be done at this time. (After a second look, it might be that the risorius muscle was affected on your left side as well, but I would need to see the dynamics to determine all this.)

Dysport/Botox for masseter reduction
Dysport will last for 3-4 months in the treated muscle. If your asymmetry is from improper injection, then it should improve as the Dysport loses activity. Follow up with your physician, as the facial pain, numbness and pattern of your asymmetry is a bit atypical and should be further evaluated.
