Just observing....
You have some decent advice in front of you for a problem that you seemed unsure about... but want to argue that the people you ask arent vets? I mean... you're probably right.... most arent vets... But they ARE trying to help you... If your "waste-hole" looked like that... and stayed like that... would you just kinda wait it out and see if it went away? Not me...
The best advice is to actually TAKE it to a vet.... Not everything has a perfect home remedy that takes care of the issue...
