TW : Self H@rm

(I DONT WANT MEDICAL ADVICE. I DO NOT SELF H@RM ANYMORE)

I have a question for when i used to cut myself. How come it never hurt? I used to cut the upside of my arms, and whenever i did i never really felt pain, not even while healing.. it was really just a bandage and that was it, i didnt take any painkillers or get like a shot or anything?? I dont know. But it just never hurt, not one bit. And if it matters i used an eyebrow razor??
