Do you also have a problem with constipation? Constipation does not mean hard stools necessairly but it can also mean not being able to get enough stool out. IBS is a real diagnosis, even though it is a diagnosis of exclusion (fibromyalgia is also a diagnosis of exclusion but I assume you would consider that a real diagnosis and it has many treatments). It is considered to be a motility disorder. There are causes of IBS and there are many treatments (including things like prescription medications) to help with IBS. You might also have pelvic floor dysfunction which I would recommend researching.
Also, I have no other symptoms.
From what I understand though, IBS isn't a real diagnosis, and is just a term given to any condition which has certain symptoms. I would like to actually determine what the cause of the problem is, and try to fix it. Any thoughts?
Yep, you're right, change that l to a c.
Feeling of incomplete evaluation should be read as feeling of evacuation.
Welcome to the gastroenterology community! IBS or irritable bowel syndrome has a common symptom of "feeling of incomplete evaluation". Have you seen a gastroenterologist about this? I would recommend undergoing some testing to determine if this is the problem or if there is a different problem.
