Hi again hun.
I would lay money that the C word isn't even in her thoughts at all. If she had any notion of that, she wouldn't sit on it, and from what I understand, cancer just does not present with your symptoms.
I did want to ask if you had been sexualy active of late, but felt it a bit too personal! The reason is that sex can DEFINITELY bring on thrush and
also irritate and upset the labia, so it could be either or going on.
I have had this several times after being with my boyfriend who lives abroad. Because we are infrequently 'together' (ahem..so to speak) I also suffer this kind of irritation or thrush afterwards. I have experienced the burning skin as you mention, and also have a tendency to get a UTI too, so have the burning when weeing too.....oh the joys of womanhood!
Thrush in particular can be a REALLY, REALLY stubborn bugger to get rid of. It does often take the application of meds to be very consistent for several days, sometimes much longer to knock it on the head.
Sexual intimacy will also make the burning feel worse, but also you can or may have JUST irritation from being sexually active, depending on how active you are, as it were.
I would see how things go as your doc said. Keep going with the cream for the moment, as it could just be stubborn. If it doesn't calm down from the cream, it may well mean that it isn't thrush at all, but I'm absolutely certain as certain can be that you don't have ANYTHING serious or untreatable. i have had all of your symptoms, and it all calmed down, so please don't worry.
As for the worry about any exams or cameras, that won't happen I am sure. A swab could happen if there is something to swab, but I promise you that whatever the case, this is doubtless solveable.x
