So first, I absolutely love that it just says hemorrhoids.

Your butt’s got a lot of veins and nerves in it just like everything else. But when it’s subjected to a lot of pressure ( sitting on the toilet with the added pregnancy weight, straining really hard during a difficult bowel movement, or else sitting for too long ) they become irritated and inflamed.

Will be itchy and can be painful and bleed. Must see a doctor for prescribed medication.
