Sore on rear end

Hi! First Post.

A months ago I noticed a lump near my back end, it’s just inside the crack and top of leg. It had eventually turned into a head which I managed to squeeze. Since then it has been weeping quite a lot. I’ve tried dressings etc etc and creams. I don’t know if it’s because it’s the proximity to where I wipe or due to straining that it’s taking a while to heal or that it’s just in an awkward place but it’s taking ages to clear up. It’s not sore as such just uncomfortable . Any ideas as to what it could be? Getting to the point where I am going to get it checked out but a bit anxious about the doctors.

Thanks!
