Numbness-Is it normal?

I did my first electrolysis session today- she used Blend Electrolysis also known as Thermolysis/Galvanic electrolysis. She started on my right cheek and jawline area. 10 minutes into working consistently in that area I started feeling numbness on my right cheek and around the right side of my upper and lower mouth.

When I told her I was feeling numbness she stopped because she said that was an abnormal reaction. It’s been 6 hours and the numbness on my cheek has subsided but the numbness around my mouth is still kind of there. Is that normal?
