Why does it feel good hurting myself?

If you look closely at the reason why you are hurting yourself, it will be quite clear. What you sense as "feel good" is not actually a good sensation. People resort to self-harm usually when they are going through some mental stress or a mental health issue that is too difficult for them to deal with. At that point, they would rather experience physical pain than having to deal with the immense mental pain. The mental pain, at least for a few minutes gets dissolved in the storm of physical pain. You get some other point to focus on than the issue at hand. So, you feel like you "feel good" while, actually, it is just taking your mind off the issue at hand for sometime, which is, not a healthy way to deal with the situation.

When you hurt yourself, your body releases endorphin which is what makes it addicting and feeling good. After a certain amount of time, your mind will get used to it and think it's a good thing and sometimes even that you need it when you don't.

When we are in pain the body produces natural painkillers to help us cope. When some people self harm the rush of these chemicals feels good

everything in life is based on personal preference. you possibly like pain but pain is not a good thing. don't beat yourself up too much its not healthy

It's actually the physical pain dominates over the mental so you tend to give priority to the physical and it gives a good feeling.

It feels good hurting yourself because you're paining yourself into existence, personally I'd imagine it as relieving mental pain out through the physical wound. This is not easy to stop at all.

It can provide a mental release from the world and help you calm down since it is a coping strategy. A negative coping strategy, yes, but it helps to free the mind and get rid of unwanted emotions nonetheless. It may feel good while you’re doing it, but it can have damaging long term effects that may cause you to only do it more to get rid of the regret and pain that comes with it. I recommend looking at some more positive coping strategies, specifically physical ones, since self-harm is a negative physical coping strategy, and it’s easier to transition to positive coping strategies when it’s the same type as the negative strategy you’re trying to replace.

Honestly, it can be all about control and feeling something in general. It feels good to hurt yourself because it is pain that you can control and because of the fact that it means that you are feeling something. When everything else in the world is out of control and you feel like you can not handle anything else, that is something that you can control. It can be good to feel something when you are feeling hopeless or numb to everything else and so hurting yourself makes you feel good because you are feeling something, anything at all.
