I don't know whether you ever sorted your problem Goldie but maybe you need to try something homeopathic.  Maybe change your diet too to see if it changes your discharge. Cut out c**p especially sugar. Eat lots of plain yoghurt with live bacteria.  Failing that go to a Genitourinary Urinary Clinic. You don't have to be referred your Gp. I had a horrible problem a few years ago and was diagnosed with a condition called Pain Syndrome. Diagnosed by a consultant. I had burning and a horrid cold feeling around my vulva area. I felt suicidal. I was treated with Amitriptyline and it did work. However I did not have any discharge. Sometimes I think consultants are rubbish and not very good at thinking outside the box. I was well supported at the GUM clinic. (Genitourinary Medicine.).
