Bumps that have formed under your skin and will not break through are called cysts. Cysts are not harmful, and may go away on their own. Some may pop and drain on their own, but they can be removed at home by draining them. Cysts are formed from an infection, foreign bodies or clogged oil glands. By removing your own under-the-skin bumps, you can save money from doctor visits, and have smoother skin.
Wash the needle and the area around the bump thoroughly with warm water and soap. Make sure the needle and the area are clean and dry before proceeding.
Wet a washcloth with warm water and position the cloth so that it is under or near the bump.
Pierce a small hole in the bump with the clean needle and allow the fluids to flow out of the bump. Catch all the fluids with the washcloth. You may need to squeeze gently on the sides of the bump to get all the fluids out.
Completely clean the area of the skin with warm water and soap. Put a bandage over the bump to prevent it from getting infected.
If you are uncomfortable doing this on your own, or you want the bump to shrink instead, see your doctor.
If the bump is continuously growing, or causing a lot of pain, see a doctor immediately.
