Hi,
Thanks for posting your query.
I am Dr.R.K and I am pleased to assist you.
Yes you have signs and symptoms of chronic
fissure in ano. You doing the right thing by taking laxatives and applying diltiaz anddoing sitz bath.
But in spite of doing all these, if you still get symptoms, then it is time to go for surgery.
In fissure in ano, the anal sphincter goes in for spasm. In the surgery done, the sphincter is cut which will provide relief.
so if you think medications and sitz bath are not providing relief, then go for surgery.
I hope that answers your question.
Regards,
Dr.Ratnakar Kini
