People
refer to tender, red lumps that may ooze pus as boils. A single
"boil" may be a ruptured cyst or a small abscess. Most boils
can be treated by "incision and drainage", a minor surgical
procedure to open the boil and to drain the pus. Antibiotics are not
needed by mouth.
Some people have multiple or recurrent boils. These boils are
usually staph infections (furuncles or carbuncles). The bacteria are
usually picked up somewhere and then lives on the skin, crowding out
the normal, harmless bacteria we all carry on out skin. The source may
be a family member, a pet or just appear "out of the blue."
In these cases antibiotics are taken by mouth for 10 or 14 days. In
stubborn cases two oral antibiotics plus topical antibiotic ointments
are usually required to eliminate the bacteria.
Gentle heat, provided by a moist, warm wash cloth held over the
area for 20 minutes three times a day, speeds up the healing process.
Putting antibiotic ointment (Neosporin, Bacitracin, Iodine or
Polysporin) on the boil will not cure it because the medicine does not
penetrate into the infected skin. Covering the boil with a Band-Aid
will keep the germs from spreading.
If your boil does not improve within 3 days after after treatment,
please return to the office. Sometimes the bacteria are resistant to
the chosen antibiotic.
A milder version of boils is folliculitis. This is an infection of
hair follicles, usually with staph bacteria. These often itch more
than hurt. The appearance is similar to acne pustules.
