Drilling a hole in daughter's toenail

[Dex]

My ex called me this morning and said that my 4 year old daughter dropped a toy on her toe last night. I haven't seen it yet, but apparently this morning the toenail is blue, the skin around the toenail is red, and it is "throbbing" (my ex's interpretation of what my daughter was trying to tell her it felt like).

My ex called the doctor and the doctor recommended to bring her in so that he could drill a hole in my daughter's toenail to relieve the pressure.

Has anyone had this done or heard of having this done?

The thought of this being done to my daughter kind of freaks me out.

I just want to go give her a big hug.
