The most important thing you can do to prevent abscesses from forming is to clean and take care of any breaks in your skin. The skin is the most important defense you have against infection. So if you fall and cut yourself, then make sure to clean the cut well, and use antibiotic (such as Mupirocin) ointment when dressing the cut. The antibacterial soap will also help.
If you are developing a lot of these abscess without any particular injury
, then you should probably be evaluated for an immune system deficiency. An example of a disease that results in many abscesses is chronic granulomatous disease. This disease is a impairs the white blood cells ability to kill bacteria. I think the likelihood that you have this is low, because you aren't reporting any other symptoms such as recurrent pneumonia
I would suggest that you schedule an appointment to see your primary care physician
. You can start by having a full physical exam done to look for any small abscess brewing that can be taken care of before they get too big and ugly. In addition, you can have a nasal culture for MRSA done. This culture looks for MRSA colonization which may make you more susceptible to developing a MRSA abscess in the future.
