I have been experiencing a sharp pain in the very bottom of my j-pouch, where the staples are. It feels a lot like a needle. If I just wait it out then the pain goes away. It's not a need to empty my j-pouch. Has anybody else experienced this? I do not want to bother my doctor's office if it just a regular pain. I have had the j-pouch for a year and a half now. Thank you in advance for your insights.
