I have had IBS and diverticular disease for up to forty years, I am 68 years old, female. Almost everyday especially after food, any food I have to go to the bathroom several times. I have had every type of test they do over the years, the most recent November, 2015. But I now seem to have an ache right done the bottom of my tummy, it used to be now and then but I seem to get it a lot now. The diorreahe pain goes when the attack goes which is a completely different pain, do yo know why I should have this. Thank you.
