HI, I am a 31 year old white female, one child, 21 years old, no medical conditions other than treated mild anxiety/depression.For the last 4 weeks I have had acidic, orange, burning diarrhoea, which has caused my perineum to be very irritated, red, and almost slightly thickened?It hurts really bad then pass either urine or stool as well as when I wipe after either, basically any touch at all stings like hell.
