I'm using vagifem daily now, after a long spate of recurring thrush last year I've not managed to get it back down to 5 per week, sometimes manage with 6 a week but sore a bit the day after not using so not worth it. I've always been worse externally and was diagnosed with Lichens sclerosus years ago and was prescribed Ovestin externally as part of that treatment daily, with steroid cream (Dermovate) as needed. I can only use Ovestin at night though as it still stings even after using for years and I have to apply Bepanthen over it to stop the stinging, I'm super sensitive.
I applied a small pea sized amount last night instead of a fingertip amount, it didn't sting as much, obviously less to rub in and still ok this morning with no irritation. Perhaps i was using too much and less is more in this scenario. I'll see how it goes.
