I'm not a doctor, but I have had so many of these symptoms that I feel qualified enough to comment. Bleeding from the bum can be serious, but not necessarily so. If you have had a lot of constipation, it can cause piles, which sometimes burst; messy, but not usually dangerous. Alternatively, it can be an anal fissure, now that really is a pain in the bum. I have had that, believe me you will know if that's it. Lots of bright blood, agony to wipe, you really get frightened of going to the loo, which just makes it all worse. Internally, diverticuli [got those too] can bleed, potentially serious, but almost everyone has them at 60+. Mainly caused by straining. Leaving the bum and bleeding, Hiatus hernia is much further up the system, so blood isn't usually a problem. Inguinal hernia, I've had that too, is much more common in men, but does occur in women, and again straining on the loo certainly caused mine. It's not really a problem if dealt with quickly, but needs a full operation. It can be done with a local anaesthetic, but they showed me the needle, like a horse syringe! They actually knock you out to apply it. The surgeon and anaesthetist were ever so chatty, during the op., but I have to admit it wasn't like a social gathering.
