I think you should see a CRS or GI AS SOON AS POSSIBLE !!!! Whatever you have is not normal occurrence and can also indicate bacterial infection !!!!! Ask your GP to do at least culture of the leaking fluid - for god sake - what is WRONG with doctors - yes - most of them are crap !!!!!! I am sorry to runt here now about doctor's incompetence , but reading all of those stories is just driving me nuts !!!! Whatever it is - yeast or bacteria or just a mucus - it can be examined under the microscope and cultured and correct diagnoses made !!!!!
I am so sorry that you have to suffer with all of that going on on such a sensitive area :( - please ask for referral to a specialist. I hope that dermatologist will see you soon and please don't leave the office without him taking a sample of your discharge !!! They are all so fast to hand out a cream and send you home "to try" and see if it will help . It is like trying to shoot a deer in the forest by using a bird-gun and being a blindfolded !!!!
I wish you the best of luck !!!!
PS: And what they plan to do about impaction ????
