The bleeding can be in droplets or in a spraying manner; the second is the prolapse of the hemorrhoidal nucleus, which can protrude outside the anus during bowel movements; the third is that once the hemorrhoidal nucleus has prolapsed outside the anus, symptoms such as moisture and itching around the anus may occur.
