It can get worse. I had that on my face and have a bunch of scares left over. I went to dermatologists, beauticians, used creams, oils etc. The only thing i didn't do was that accutane or whatever medical thing is because its a pretty serious med with tons of harmful sides. Fortunately i don't get them anymore, but i will get 1 once in a while on my back. Can't really help you with answer though dude cause i've just learned to deal with them (hell i'm just happy they are on my back and not my face). One of the people i went to was this beautician lady who specialized in very problem skin like i had. She used a lancet to make small, controlled incisions and drain them. She explained to me that if done properly this minimizes scarring and helps healing. I don't know if it really helped because i already had a bunch of scarring by the time i found her but i know i didn't get any worse.
All the dermatologist did was spray me with some cold spray (like nitrous oxide or something) and give me some bullshit cream. Then she charged me like 3 times what the beautician lady did per session.
