I used to have regular acne, but that has generally gone away now. However, I now have this similar condition (but only on one half of my neck), where I get these hard white little bumps at the base of a hair. I usually puck the hair out, which usually pulls a portion of this white thing out of my skin. I usually then tweeze that out, which is very painful, but provides an instant relief once removed. I would describe what I pull out as something that looks like a small piece of white rice. It is long, thin, and incredibly tough - once removed it leaves a little hole in my skin which takes a few days to heal.
I have been to several doctors who all just say "ingrown hairs." However, sometimes I get these in a follicle where there is no hair growing, but just this white thing. I also tend to get them in groups. Usually if I find one, there are a couple others nearby.
I have been on antibiotics and pretty much every topical there is, but they just never seem to stop. Please help!
