Hi there...most probably due to fissures which are secondary to constipation or hard stools...help keep stools soft and improve fissure healing. Fiber-rich foods include fruits, vegetables, nuts and whole grains. You also can take a fiber supplement. Adding fiber may cause gas and bloating, so increase your intake gradually... Drink adequate fluids. Fluids help prevent constipation...Exercise regularly and Sitz baths after bowel movements and as needed provide significant symptomatic relief because they relieve some of the painful internal sphincter muscle spasm...Consult nearest surgeon once for clinical examination they will guide you further.
