I have had my ears drained several times, and this is by far the best way to do it.
Make a small cut on the ear (very small)
Squeeze the puss out (its going to hurt a bit)
Take and break off a small piece of a toothpick and stick it in the cut on your ear so half of it is in your ear and half is out. This will keep the small cut open.
Squeeze out every few hours for about a day after and you should be good
This is much better than sticking yourself several times, trust me.
