Hi Jack,It sounds as if you're concerned about
the consistency and shape of your stool, which seems to warrant a trip to your doctor. IBS is certainly a possibility. If it's something that concerns you, and has persisted for quite a while, it is time to call the doctor and make an appointment. No point in second-guessing what's going on with you. Please let us know what you find out. That's how we learn! Wish I could be of more help, but I really don't have a clue.
Here is a website that has lots of info on the topic. It seems quite helpful, although I am not familiar with the source. Check it out:
