Suggest Remedy For Vaginal Itching

I constantly have been getting tonsil stones for the last 5 years. It has been getting worse, to the point where i am removing them, 3 times a day. I have gone to see 2 ENTs and they say I don't need to get a tonsilectomy. It is interfering with my life because I am a nursing student and in close proximity to others and I have very bad breath. For the same amount of time I have also been experiencing vaginal itching and have been had a yeast infection at least twice a yr. I take the antibiotics, but the itching persists. I have never had sex and have been tested and am neg for STI's. I am wondering what remedies I can use for both of these ailments and if they could be conected in anyway. Do I have more gram neg bacteria in my body naturally? I just need some help. This is really bothering me
