So I'll get right to the point. For about two years, on and off, I get big painful pimple like bumps on my pubic area and on my inner thighs. Some painful and some not. The average one starts out as a hard, red lump and eventfully comes to a head, being very painful. Washing with soap and water doesn't help. In fact, antibacterial soap makes it 10x worse. It all started when I first shaved down there. I shaved with an electric trimmer and I got one. That was the first and the worst one. It was so bad that I had to change out the band aid 2 to 3 times a day. Ever sense then, I get them every month or so and they're sometimes painful, sometimes not. I've looked it up and all I could find was maybe it being cysts. But why has it been going on for 2 years? I even went to the doctor and got a cream for it like a year and a half ago. Didn't help at all. I don't know what to do about it. I have dark purple scars from it and it's just bad to look at. So what i'm asking is:

What are they? 

Why are they there?

should I go to a doctor?

and how do I treat it myself?

I hate this problem. It honestly makes me self conscience even though no one can see it. Someone please help me out. Any useful info would be greatly appreciated. Thanks in advance.
