You might notice worsening inflammation — redness, swelling, pain and heat — around that area. Sometimes MRSA can cause an abscess or boil. This can start with a small bump that looks like a pimple or acne, but that quickly turns into a hard, painful red lump filled with pus or a cluster of pus-filled blisters. Not all boils are caused by MRSA bacteria — other kinds may be the culprit.
Rely on a professional to drain a boil. Do not try to squeeze it or drain it yourself. If a minor skin injury starts to hurt — a lot, much more than seems normal — be on the lookout. Cellulitis is a deep skin infection caused by staph or streptococcus strep bacteria, including MRSA. This is called "colonization" or "being colonized. A sign of a staph skin infection is a red, swollen, and painful area on the skin. Pus or other fluids may drain from this area.
It may look like a boil. These symptoms are more likely to occur if the skin has been cut or rubbed, because this gives the MRSA germ a way to enter your body. Symptoms are also more likely in areas where there is more body hair, because the germ can get into hair follicles. MRSA infection in people who are in health care facilities tends to be severe.
These infections may be in the bloodstream, heart, lungs or other organs, urine, or in the area of a recent surgery. Some symptoms of these severe infections may include:. A cotton swab is used to collect a sample from an open skin rash or skin sore. Or, a sample of blood , urine , sputum , or pus from an abscess may be collected.
The sample is sent to a lab to test for identification of which bacteria are present, including staph. If staph is found, it will be tested to see which antibiotics are and are not effective against it. This process helps tell if MRSA is present and which antibiotics can be used to treat the infection.
Draining the infection may be the only treatment needed for a skin MRSA infection that has not spread. A provider should do this procedure. DO NOT try to pop open or drain the infection yourself. Keep any sore or wound covered with a clean bandage. Severe MRSA infections are becoming harder to treat. Your lab test results will tell the doctor which antibiotic will treat your infection. Your doctor will follow guidelines about which antibiotics to use, and will look at your personal health history.
MRSA infections are harder to treat if they occur in:. Be sure to follow instructions on how to care for your infection at home. How well a person does depends on how severe the infection is, and the person's overall health.
Pneumonia and bloodstream infections due to MRSA are linked with high death rates. The sample is sent to a lab where it's placed in a dish of nutrients that encourage bacterial growth. But because it takes about 48 hours for the bacteria to grow, newer tests that can detect staph DNA in a matter of hours are now becoming more widely available. Both health care-associated and community-associated strains of MRSA still respond to certain antibiotics.
Doctors may need to perform emergency surgery to drain large boils abscesses , in addition to giving antibiotics.
In some cases, antibiotics may not be necessary. For example, doctors may drain a small, shallow boil abscess caused by MRSA rather than treat the infection with drugs. While you may initially consult your family doctor, he or she may refer you to a specialist, depending on which of your organs is affected by the infection.
For example, he or she may refer you to a doctor trained in skin conditions dermatologist or a doctor trained in heart conditions cardiologist. During your physical exam, your doctor will closely examine any skin cuts you may have.
