There may be pain too especially if the stool is hard.This could be due to the hard stools pressing on the swollen piles or due to a tear in the inner lining of the anus.3. A painful swelling or a hard lump around the anus may occur when a blood clot forms.This condition is known as a thrombosed hemorrhoid.4. In addition, excessive straining, rubbing, or cleaning around the anus may cause irritationwith bleeding and/or itching.How common are hemorrhoids?Hemorrhoids are very common in both men and women.About half of the population have hemorrhoids by age 50.Hemorrhoids are also common among pregnant women.The pressure of the fetus in the abdomen, as well as hormonal changes, causes thehemorrhoid vessels to enlarge.For most women, however, hemorrhoids caused by pregnancy are temporary.How are hemorrhoids diagnosed?1.
