Is putting tight rubber bands around my arms to hurt myself a bad idea?

I've cut off the circulation to my hand for about 20 minutes but my hand changed colour a bit and felt strange. People convinced me I had to take it off because it was bad for me to have it on and I never did it again. I don't think it's bad for a few seconds and most of the pain is probably then but the longer the time the worse it is. cry so you can feel okay.

You are real stupid! of corse it could hurt you if you do it to long your hand can be plarzid!! do you realy want that just to realve stres. try something different.
