Hello, I was on the toilet this morning when I felt a slight bit of pain. There was no blood but I did feel a small pimple like bump near the inside of the anus. I checked the mirror and it is about the same color as my skin tone. However, some forums say it could be hemorrhoids. Should I be worried or Will it go away naturally? If it helps, I did have diarrhea a few days ago but only felt this today.
