Butt crack problems can be difficult to heal on your own and the infection can spread inwards.
As your parents to make an appointment and take you to see the doctor.
The doctor will be able to examine the butt crack and see exactly what it is. As it has been itching and you have seen "flesh like things" inside, there may be an infestation of worms or a parasite and that can cause itching.
Itching and scratching can become a vicious circle. So the more you scratch, you damage the surface of the skin, and then the more it itches.
Although it is embarrassing for you, the doctor will have seen a lot of all body bits so do not worry about that. As you are 15, you will probably be too embarrassed to let your mum have a look.
Get seen to by your doctor as soon as you can, these things can fester and get much worse. So the sooner you get seen the sooner you will be able to get it sorted. Make sure that you wash your hands every time after you have used the toilet or touched yourself down below. Always wash your hands before eating any food and wash fresh raw fruit and vegetables before eating them.
Let us know how you get on.
Best wishes.
It's possible that this could be an insect bite. If you're still having itching and bleeding you really should tell your parents about this so they can take you to the Dr.
ive had it for 2-3 weeks and before i tell anyone i want to be sure that i cant do anything about it myself. thanks for the response though.
I was thinking a possible boil too when I first started reading your post. They will start off kind of like a pimple, get a big pus head and then pop drain and heal. This can go on for a couple of weeks. You say you've had it for awhile, how long ?
I really recommend that you talk to your parents about this and then see your Dr. There is no need to be embarrassed.
