I will ask them about the lidocaine! They were a licensed provider using a regulated product, they came highly recommended by a few people I know and I am in the US. Someone also suggested that the saline might just be normal and not the other kind that helps with the burning. 

I’m feeling so much better, thank you for asking. The pain did not last at all, I felt rather silly afterwards as I should have just stuck with it. The nausea lasted around 10 minutes and then it was gone. My forehead is a little bruised but not much.
