A staph infection is generally characterized by pimple-like bumps or blisters on the skin surface. These bumps are often accompanied by swelling and reddening of the surrounding skin area. At the center of the lump is a white or yellowish pus-filled head, which occasionally drain and heal on its own.
Boils caused by staph infection are often itchy, tender and warm to touch. These blisters can turn into painful, deep sores. If ignored and untreated, there will increased pain and swelling. The color of the skin surrounding the affected area turns from red to purple, and may gradually spread as the infection worsens.
Staph infection and MRSA are diagnosed by two traits. First, the emergence of enlarged boils filled with pus. These boils may grow in size and have multiple heads and are called carbuncle. Draining these boils at home is not advisable since the secreted pus may spread and worsen the infection. In few cases, abscess may also form. These are cavities under the skin which are filled with pus. These boils do not drain on their own. One can feel the fluid inside an abscess on pressing a finger on it. It is very important to develop good hand washing habits and appropriate hygienic habits to prevent the spread of the bacteria. Second, is folliculitis, which is similar to boils. The difference between a boil and folliculate is that folliculitis is an infection of a hair follicle, which is usually less than a quarter inch in diameter. In some cases, folliculitis is often surrounded by inflamed skin.
However, a confirmed diagnosis can of staph infection or MRSA can only be done by way of a laboratory bacterial culture.
