I looked up ibs and the symptoms sound similar to what I'm dealing with. Ill also have it where after not being able to have a bm for a couple days ill have a normal bm and then a few minutes later have a bit of diarrhea. I guess its from being backed up...I don't know. I'm just getting frustrated with these symptoms and the fact that the specialist I was referred to can't see me until early january. I'd really like to get a medical opinion sooner than january.
It sounds like you have IBS. Some people have IBS where they only get diarrhea, some have it where they only get constipation, and some alternate between the two. The only thing you can do at home is to adjust your diet. Many people with IBS have trigger foods (which are different for each person). You might want to experiment with taking different foods out of your diet to see if that helps.
Please read 'Nissen-fundolplication-pain' on this page...It applies to you also.
