Why have U been given more antibiotics?

These are known to kill the bacteria throughout the digestive system and unless a swab has been sent for testing, the GP cannot know which AB to prescribe. How many days B4 this latest result is back?. Do U feel that you require yet more ABs when none of the others have actually helped symptoms?
I would wait for the swab report and begin the appropriate VA treatment - 1 now and another this evening then every night until symptoms ease. Which mayB a long time as you've had so many problems getting this under control. Which estriol pessaries have been prescribed? I am fortunate in that ovestin worked almost immediately, initially pessaries which were withdrawn. Now I have the tube with an applicator [estriol] plus I smear a little around the urethra and labia [or KY jelly] - anything to stop the area becoming dry = itchy.
When symptoms niggle I have found that swallowing nurofen x 2 in the afternoon plus a 'extra' insertion of estriol really helps, then going into 3-5 nights of esrtriol. I've been 5+ years with this and so far it's worked in that the initial urine infection-type symptoms went with regular treatment. PHEW!
I would also ring the Surgery and ask for the appt to a menopause specialist now as there are in some areas, 12-18 months waiting lists even in the private sector. When the appt does arrive U can cancel if it's no longer required.
Hopefully some1 will be along re testosterone. VA is usually due to lack of oestrogen which may make the whole body dry: inside and out; scalp, deep in the ears, nostrils [me] skin, vagina, anus ..........
When I had thrush after stopping The Pill and 20 years later when I had emergency surgery, it was an itch that I was unable to reach! high up. Fortunately I didn't have the thick creamy discharge which can accompany the itch!!! Nor was my vagina smelly.
Let us know how you get on.
