Lately? How long?
Any other symptoms like constipation, bloating, nausea, fever (even if only slightly rised), itchy skin...?
Intestinal parasites (worms), food poisoning...Crohn's disease, diverticulitis are some common causes.
Spicy foods can cause the "burn". As a matter of fact jalapenos will with out fail cause the burn.
For me eating oranges or any citrus fruit causes a burn and the little floaties in my runny BM. Corn,slaw,and salad causes the floaties for me as well.
The symptoms of mild diarrhea include:
* Abdominal bloating or cramps
* Thin or loose stools
* Watery stool
* A sense of urgency to have a bowel movement
* In some cases, nausea (upset stomach) and vomiting
In addition to the symptoms described above, symptoms of severe diarrhea include:
* Blood, mucus, or undigested food in the stool
* Weight loss
Severe diarrhea may be a sign of a more serious illness. Contact your health care provider if you have prolonged diarrhea or a fever that lasts more than 24 hours. Also, see your health care provider promptly if vomiting prevents you from drinking liquids to replace lost fluids.
I would wait till the week is over then if it still is happening call a doctor because it might if been just something you ate
