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.
go to the hair store and get something called skin tight...its for hair bumps...garanteed to work...and about 10 dollars
