What can be the cause of constant itching and pinching in the vagina and labia? It started with a fungal infection at which I had no symptoms nothing pinched me but came out fungi in the vaginal swab. After finishing the treatment and while taking the probiotic, my vagina began to pinch inside, I stopped the vaginal probiotic and I started taking orally, but the ailments did not pass. The ailments persist for 4 months, so I have already been treated with two intravaginal preparations for ringworm and twice with drugs for oral fungal diseases, but the ailments do not go away. After the first treatment I had a swab done again, nothing was detected after a month again the same and recently I repeated the vaginal swab again and no bacteria or fungi were detected, I also did tests for chlamydia, ureloplasma, mycoplasma and trichomanos and nothing was detected, only a few lactobacillus bacteria from 10 to 50 and leukocytes up to 5 in the field of vision and vaginal pH 4.5 as well as the degree of purity II came out. I take a vaginal probiotic invag and support myself with provag cream and oak bark sit-up, but the relief is only for a few hours. What can be the cause of pinching and itching of the vagina and vulva if the tests do not detect anything pathogenic? I will add that sometimes the pinch is not also the urethra but nothing came out of the urine test and the urine culture negative only came out gram positive and gram negative in the urine culture, but the doctor claims that these results are correct. Do these detected positive and negative grams actually indicate cystitis? It pinches me only after urinating, but the inflammation should pinch during the donation and I do not have that. I no longer have the strength to bother with it another few months and every gynecologist does not know why I have such symptoms and prescribe only more drugs for vaginal mycosis and I think that since they have not been detected, such treatment does not give anything anyway. Recently I noticed only white vaginal discharge which is watery with a not very pleasant smell thinking whether it is not a bacterial infection, but in the swab of anaerobic or telene bacteria also not detected. Is a bacterial infection possible if smear and biocenosis tests do not detect anything?
