I had a fissure for at least 10 years. I thought it was a hemmroid (sp). When I was constipated OMG the pain. I didn't go to a doctor because I was embarrassed. In 2001 the pain was so bad I could barely sit, so I went to the doctor's. He said I had a hemmriod and gave me some cream for the pain, but over the following two weeks, I was still in pain. Finally the doctor got me a referral for a protologist. I saw the protologist and was told I had a fissure and not a hemmriod. The following week I went in and had the surgery. I had tons of anxeity the morning of, needlessly. It really wasn't bad and the recovery was only a day of two of mild pain. I am sure the surgeon/doc will give you something for that. I know I was given 60 pills for pain and I ended up using about 4 or 5. A few days after the surgery I realized I should have gone in years before. All those years of pain, just because I was embarrassed. I hope this helps.
