I had that problem for over a year. It turned out to be staph infection. I was told to clean with peroxide every day and leave open to air as much as possible. Also, you need ant-biotics. The dr needs to do a culture to know which anti-biotic you need to clear it up. They keep coming and you have to get them to drain and continue using perioxide til it heals. It is best to go to the dr because it will go to other parts of the body. I got it on my eye lids and they kept coming until they went all the way across, now they are in my lashes. Make sure you get him to take a culture, because staph does not react to all anti-biotics. Just writing any one out is like a shot in the dark and hoping you hit the target. Use hot compresses to bring it to a head. Go online and check staph infections and you can see what they look like. Some say it is contagious, some say it isn't. My husband never got it. Hope you get it cleared up. Let me know what happens. I am curious as to what your dr does. They leave scars, too. Go while you have the infection before it drains so he can test it. There is one MRSA. Staph can be life threatening, as you will see when you read information on it. RJ
This could be sweat dermatitis, folliculitis, allergic reaction. In most individuals there are outbreaks of folliculitis from time to time.
Folliculitis is infection and inflammation of the hair follicles. The condition may be superficial (i.e., on the surface of the skin) or deep within the follicles.The most common cause of folliculitis is infection by the bacteria Staphylococcus aureus.
Folliculitis symptoms can appear independent of infection. Exposure of the skin to certain chemicals, especially oils and tars, can trigger an outbreak. People with depressed immune systems, diabetes, or obesity have a greater risk of contracting folliculitis than the general population.
Patients with chronic unresponsive folliculitis may require investigation into the source of the infection. S. aureus bacteria can live in the patient's nostrils, periodically triggering a folliculitis outbreak.
Individuals who are predisposed to folliculitis should be extremely careful about personal hygiene. Application of antiseptic washes may help prevent recurrences. A topical antibiotic cream, mupirocin (Bactroban®), has been effective at reducing bacterial colonization in the nostrils. It is applied twice daily for a week and is repeated every 6 months.
If there any of the mentioned medical causes then treating those will reduce the occurence of the condition.
Some stubborn cases of folliculitis have been responsive to laser-assisted hair removal. This process uses a laser to destroy the follicle. This reduces the scarring that results from folliculitis.
