Mysterious Sore Bump On Rectum

You may well have a hemmorroid. Have you ever had a child? Sometimes they pop up afterward. Sometimes they just appear on their own. Go to the doctor, sweetheart. You don't need to have to worry unneccessarily.

This does sound like a hemorrhoid. They are very common - 40% of adults in the US will have them at sometime. But they are VERY annoying and if they become chronic they can become serious. Drink plenty of water and eat lots of fruit and veggies to avoid constipation. Wipe yourself thoroughly but gently - try using Baby Wipes! You can try over the counter creams like Prep H. If that doesn't work there are many natural hemorrhoid treatments. I have a site devoted to helping people with hemorrhoids.
