Hi, Im 15 years old and for a while now Ive been having these cyst-like bumps on my inner upper thigh and butt. Sometimes theyre very hard to squeeze, but when something comes out of it, its usually like a yellow, white -mostly white pus that comes out it. And I get pimples on my butt. Recently Ive had a cyst like bump one on my butt and it was very hard and dark, though when I was able to squeeze it, a white cheese like substance came out. As well I have boils, but I dont sit on public toilets seats or anything. As well i have a lot of black heads on my inner upper thighs, and I can feel big nots-bumps under the skin that most of the time surfaces and I can see the cyst like bump, but then it may go back under after a few days or it may just go away. Also I have these dark dots on my inner upper thigh that are dark, hard dots. Oh and one more thing; these cyst like bumps on my inner upper thigh and butt sometimes hurts. Like I cant sit  down properly cause it hurts - but its not all the time. And sometimes they have like raw skin and it burns and hurts to touch them- especially on my upper inner thigh. And sometimes blood will come out of them when I squeeze them. I am not sexually active. I try to be as clean as possible. I just want to know what this is and whats causing it, and how can it be stopped. Its very aggravating, I cant wear shorts or anything, I only wear jeans. Please and thank you for you help.

Namaste Welcome to Chat Doctor Greetings of the day You are probably suffering recurrent folliculitis in the buttock area.  Other possibility I would like to consider if you are very hairy and sit for prolonged time is Colonial Sinus.  Both of them require assessment by General Surgeon.  It will require a course of antibiotics like Augmenting for 7 - 10 days., local ointment, hot sat bath.  If it turns out to be Colonial sinus/ fistula in ANO it will require further surgical intervention.  Any case you need to see a Surgeon. Do get back if you have any doubts. Take care Regards
