I remember years ago I used to go to my pharmacist in Spain armed with a urine sample and I always tested negative and couldn't understand it and one day he said to me you must see gp as it will be your ladybits,I was really embarrassed and couldn't wait to get out the shop and didn't think to ask him any advice on what he meant,I so wish I had now I'd have saved myself so much grief.V.A is so horrible and I believe most of these ladies on bladder forums are suffering from v.a and don't know it,they are having invasive procedures done and being left with worse problems due to bacteria being introduced during all this fannying around and at the end of it all being referred to pain clinics after all these instills and stretches leave them in even more pain.it took me 6 months at least to heal my bladder to an acceptable level and they will never get me down that route again.You must get your urine ph levels as neutral as you can and the only way to do this is by not eating acidic foods and drinking fresh water with a wee bit of lemon juice in it,research bladder friendly foods and follow this to the letter.as DG says no caffeine no spicy foods no perfumes downstairs,bottle wash after peeing and wash after pooing.buy bleach free toilet tissue,you can get from amazon,I have to do all these things,at first it's a pain then as time goes on it's as natural as taking your hrt.if your still suffering do a vagifem boost for 14 nights again and every single day use that lubricant till it settles down again,it's a lifelong curse now so you have to keep working at it,I've developed sensitivity to 4 antibiotics now after overuse of them so I'm scared of getting sick and needing an antibiotic now as it'll be a struggle to find a friendly one,don't let that happen like I did,keep on top if it yourself the docs are useless.good luck xx
