I have been chronically constipated for as long as i can remember (I'm 18), and since about 2 months ago, after passing extremely large stools, i would have something stick out of my anus. I would painlessly push it in and go about my day, but since 2 days ago, it's gotten worse and now it won't go back in for more than a few minutes, and it's getting harder to push it back in. It doesn't look like how i'd think hemorrhoids would look, because it's sort of big, like a mini marshmallow. I've been reading about what it could be and i've come across rectal prolapse, but that's been described as being "blood red", and what i've got seems to be just about skin colored. I'm freaking out. Somebody please help.
