Abscesses go through several stages as they develop. In the beginning, the area may feel tender or itchy. As white blood cells rush to the infected area, pus begins to collect. At this stage, the abscess will become more swollen, painful, and warm to the touch. A visible lump may appear, and the area will be red and inflamed. As the abscess matures, the lump will become more prominent. At this stage, you may see a white or yellow head form on the surface. The pain may intensify during this time, and the abscess may start to feel “full” or tight. If left untreated, the abscess may burst on its own, releasing pus. While this can relieve some pressure, it doesn’t mean the infection is gone. Medical treatment is still needed to ensure proper healing and prevent further infection. After the abscess is properly drained, the swelling and redness will gradually subside. Your healthcare provider may prescribe a round of antibiotics to prevent the abscess from reforming or the infection from spreading.
