I had constant pain from a
fissure for about 8 months. It was so unbearable, after trying every known therapy from diet modification, rectogesic cream, scheriproct cream, acupuncture, chinese herbs, natural medication, I opted for LIS surgery. I chose a surgeon who had done 100s of these operations with no problems.
After the LIS surgery I was in a lot of pain for the first week and constipation didn't help matters. Then the next couple of weeks I was feeling better.
