It can be messy until the vagina settles.
My symptoms were intermittent urine infection-type symptoms: antibiotics did ease treatment but a urine sample, eventually sent to a Lab., grew nowt. My GP advised VA treatment and ovestin has been successful. When I feel the need2P I take 2 Nurofen 3 times a day to ease the nip.
Some require nightly treatment, regardless; as well as 'yes' or 'sylc' or other soothing balms on the outer labia area. I find KY jelly adequate.
Once the vagina settles with a regime, stick to it ;-). Let us know how you get on and don't be fobbed off by medics saying that we can't use VA treatment more than twice a week!
