With out examination its hard to suggest I would suggest you to consult nearest surgeon for clinical examination they will give you full information...Add fiber to your diet. Eating about 25 to 30 grams of fiber a day can 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...and exercise regularly.. Good luck.
