I've missed 2 times that resulted in PAINFUL abcesses. OWWW! Although I prob should have gone to a doc, I just put a warm compress on them and lanced them myself. Again-OWWW!! And also-EWWWW! Syringes actually help to get the draining of the pus started. After placing a hot, wet washcloth on the area for awhile, if it's getting ready to be able to drain, there will be a softer spot in the center of the hard abces. Get your syringe, grit your teeth, and stab it in! LOL If you're in the right spot, when you pull back the plunger (SLOWLY!), it'll start filling up with goo, and leave a lil hole for continuing the lancing process.
PLEASE REMEMBER: This is just my own dumb at home solution cuz I was too pansy ass to get help from a professional, which is OBVIOUSLY the best option.
