What type of hemorrhoid surgery did you have? Pain is the most common reason why patients avoid hemorrhoid surgery – therefore, although it is not technically a complication, pain is an important factor in discussing surgery as a treatment option. Unfortunately you are finding this out first hand. Management of pain frequently includes the use of opiate pain killers, such as morphine and morphine-like painkillers Morphine can be delivered either as an epidural (that is solution of morphine delivered directly to the dura layer of the spinal cord through catheter), injection, IV drip, and even a pump installed under the skin.

The fact that it keeps coming out, is something that you need to check on with your doctor right away. I know there are several others around here who have had this surgery and will be able to share personal experience with what they went through. Call your doctor though and see what is going on.
