Basically if it is of long duration, then surgery is only cure in fissure where as you can try medication in piles provided you are bleeding a lot

Hi dear if this bleed is not associated with pain than is generally due to piles and quantity of blood should be more. If this is associated with pain and quantity is less than this is due to fissure. You should avoid constipation, as this is the cause for piles/ Fissure. it's better to get evaluated , a short scopy done to rule out the underline problem.
