While at the moment I am guilty of self-diagnosis as I have not found the chance to visit a derm, I can't find any other condition that looks like what I have.

For many, many years now I have had tiny, raised, skin-colored bumps on my abdomen from underneath the breast area to the bottom of the ribcage (no lower than that). They do not form a whitehead, are very small (a couple millimeters across) and hard--I can't pop them and trying to extract them with a needle or tweezers would require me to dig quite deep and would be very painful. From time to time one or two will become inflamed and form a larger cyst where the entire area around is very tender to the touch. I've tried lancing one of these and only a small bit of cheesy fluid comes out, and the whole area turns a purplish scarred color for several weeks (most likely bruised from the amount of force needed to break through all those layers of skin!).

Like I said I believe they are ingrown vellus hair cysts even though I have not recovered any hair from the highly inflamed ones (the smaller ones I am too scared to try) and lately more have become inflamed. I used to get one every few months or so, but recently I had three of the cysts become large and painful in the span of a month. Is there any at-home treatment or regimen that I can follow to decrease their occurrence? I haven't been able to 'track' them to see if they fade after a while, so I'm worried that eventually they may all become inflamed and painful.
