Yes, I have had some yellowish, brownish stains in underwear that stains, permanently. This has gone on for a while. I am 66 years old, and have had inconsistent bowel habits for a while. I usually depend on stool softeners, in order to have bowel movements on a consistent basis, and then they are light. I feel fine, and do not have any uncomfortable feelings, if I don't have a bowel movement every day. Sometimes, I think there is leakage through my vagina, when I have to take stool softeners on a regular basis. Is this something to be concerned about? My mother had the same problem. Is this hereditary? I have a family physician. Should I make an appt.?>
