I am almost certain that it is not a hernia. My brother in law had one and the pain that he described was much different than this. My stools are loose. Not diarrhea or watery loose but thin, stringy loose. I'm not certain if there is blood in them or not. Its a consistent color, more brownish but maybe a hint of blood. Though it may be just a different color because of the general change in bowel movements.
After 2 days of fiber the stools solidified a bit more but still are a bit more stringy and smooth.
