Excuse me for the photo. Please take a look at what it could be and what you can do until you reach the doctor? Yesterday I had an accident in my diaper and walked around with my poop for longer time because I was not near enough to change the diaper. Yesterday I smeared Bepanthen, today it seems worse. What can I do if someone has experienced this?
