It depends on how depressed I am. If I'm really out of it, I don't usually feel the pain until afterwards. But if I'm more in reality, then I feel the pain but I ignore it. I'd rather feel pain than be numb anyway. It also depends on what way I am injuring. Usually with spraining bones I get pain right away. With the bruise it swells and I just feel pain if I bump it. With my cuts, they usually bleed through my pants but luckily no-one sees anyway. My burns don't hurt until the next say, and they take forever to do. I have a huge scar on my arm and one on my foot from the first few times that I did it.
