Thanks ladies, your kindness and understanding has actually made me quite emotional, but in a nice way, if that makes sense. I live in UK and was holidaying in Scotland so no alteration in diet that would account for it. I had had a very bland breakfast, fruit, yogurt, followed by poached egg/toast so can't understand what the trigger was. We were traveling to a wedding the previous day and I had taken Imodium as a precautionary measure, but had had a lot of food and drink over the previous few days so perhaps that could have been the reason.
It reduced me to tears, humiliation and total loss of dignity. However , I normally can plan and cope well so I'm not letting it get to me. I've had numerous investagaitons ( friend is a colorectal surgeon) and nothing sinister ever showed up. I've had muscle tone stimulus tested too, it's not great, having had instrumental delivery of first child with third degree tear, plus three further pregnancies .
Oh well, just have to adjust. I'm currently coping with the cystitis brought on no doubt by the " accident ". Isn't life fun
