so. how long are you going to tolerate this before you see a medical provider have a proper examination and get this treated? this still may be a pilonidal cyst/abscess or even a perirectal abscess. a guess of course since i can't examine you. either way you need to have this treated and most likely will need a minor surgical procedure.
i have a tiny blood lump at the end of my spine where the butt crack is. soft red pulsing. smells like poo what is it? . initially i thought it could be a pilonidal cyst but i highly doubt it. the smell it produces is enough to scare away people it is like having poop in my pants 24/7 or 3 hours after a shower. noticed it 2 weeks ago the smell was there for 2 months. just before the smell the only irregular thing i did was running a little at the gym (4 times 15 minutes in 10 days). i am 22 years old averagely fit healthy. it is a small lump like an above average zit bloody warm pulsing sweating poop smell.
