I have had chronic anal fissure with sentinel tag for 1 year, last month the pain became severe problem, especially each after defecation, deadly pain!! So, I consulted with a general surgeon, and asked me to undergo surgery! I have decided to undergo surgery( lateral internal sphincterectomy)! I have done it on Tuesday evening with spinal anasthesia, on Friday noon, I have discharged from hospital! Comparing pain br fore and after surgery is seen to become better!
