What Is The Treatment For Small Bumps In The Pelvic Area?

I am getting 4 or 5 small bumps on my pelvic area that seem to be filled with puss and blood at times, I am 36 yr old man and trim that area pretty often with clippers. Could it be in grown hairs, I seem to be geting more and more and they are sometimes tender, they ones I popped are leaving black marks
