Hi,
Popping a pimple is not the best way of getting rid of it.
It can leave scarring which I am sure you do not want.
The best way I found to get rid of them quickly is to get a washcloth and put it under hot water, as hot as you can stand and put it straight onto the pimple to draw the pus out. Keep repeating this for a few times then leave it and it will then go down.
Good Luck
