go to the hair store and get something called skin tight...its for hair bumps...garanteed to work...and about 10 dollars
first make sure to keep the area clean and dry to prevent further infection. I would do a hot pack for 30 minutes a couple times a day until you are able to bring the infection up then pop it.
If it's really bad the other thing is to go to the dermatologist to have it lanced. I had to do that.
