Over 3 days or so the pain at the bottom of my back passage has been getting worse and worse. I've looked & there are no visible signs of piles but today the pain has reached a point where it actually hurts to sit down - to be blunt it feels like someone has shoved a broom stick up me or that I've given birth through my back passage. I bought some pile cream today which so far has had no effect. - Does this sound like piles or some thing more sinister?
