Hello.
Thank you for your query at DoctorSpring.com
As per your description, it looks like you had fissure in ano. It is a crack inside the Anal canal. Due to passage of hard stool, the crack will get injured and lead to severe pain associated with bleeding.
They might have excised the fissure.
But, you should take high fiber diet.You should drink plenty of liquids. Eat fresh fruits and vegetables. Your stool should be soft.
By the above measures, pain and bleeding will come down.
Without following the above measures, you will not be benefitted with further surgeries also.
Please apply local 2 % lignocaine jelly inside the Anal canal for relief.
Nothing to worry.
It will come down.
Wish you good health and speedy recovery.
Regards
