Vaginal burning: What could it be?

If you have been checked for UTI and vaginitis and test negative, try some vitamin E cream. I am now 80 years old, and for years after menopause had severe vaginal burning and stinging. I was negative for UTI and vaginitis many times. I was given estradiol which burned then compounded estradiol which also burned. At this point, I apply vitamin E cream and at times use a boric acid vaginal capsule internally. This really has helped so much. I hope you try this and feel better.

@merpreb hi. Yes I had utilities and 3 cultures 3 meds. All clear but left with achy burning pain in vagina

UTI gone left with agonizing achy burning pain in vagina.

I have been suffering with alternating burning or itching for at least 15 years. It started roughly 10 years before menopause.
I initially thought it was pin worms, the sensation started out very light and odd - but it would escalate into a maddening itch.
I've seen dermatologists, gynos and allergists. I was diagnosed with all the things, had a biopsy. There was no treatment except to live with it. (WTH)
I didn’t want to go on oral medication, however, because the sensation would ebb during the day. Sometimes antihistimes will mellow it a bit. Probably just makes me sleepy enough to sleep through a flare.
Any creams or ointments that were prescribed ended up exacerbating the issue, sometimes to the point of chemical burns because I am now allergic to any steroid creams or gels - propylene glycol is in everything. I recommend doing a skin test on the inside of your elbow before putting ANYTHING down there. Let it sit for at least 24 hours, covered by a band aid. If you react at all, don’t use it below.
I have been mostly gluten free for 5 years. I’ve been slowly removing other foods from my diet. Dairy, nightshades, citrus and sugar are the last to go and they all cause different "zones" to flare. Some worse than others. Citric acid is in EVERYTHING.
I'm mostly whole-food diet now.
I’m hoping to work up to a sugar-detox as one person suggested here. Maybe I can heal my gut. I’ve been a huge sugar addict all of my life.
My suggestion is to skip dairy for a week and see if it helps. If not, do another week without any nightshades, then try gluten.
Oh - and get a handheld bidet sprayer to attach to your toilet.
Lifesaver.

If it's itchy then it could be fungal infection

The fall before I was diagnosed with endometrial serous carcinoma I suddenly had discomfort down there. My ultrasound showed no bleeding and only a slightly thickening of my uterine wall. I used Vulva care.

In my experience, burning is closely tied to vaginal health and bladder health. A dna urine analysis and a vaginal dna analysis should tell you what is going on, infection wise.
Plus, hormonal changes can cause burning. A hormonal test and a good hormone doctor can check this for you.

Recently I needed to change my hormones. I had had burning constantly for months with my first ever BV infection and 2 bladder infections. Seems that my estradiol level had fallen and set me up for infections and burning symptoms . I am taking oral and vaginal probiotics, continuing my estriol vaginally, hyaluronic vaginally but have introduced a low low level of estradiol. The burning stopped almost immediately, plus no more infections.

@geford have you been checked for lichen sclerosis?

@sirene Hi, yes. The steriod creams introduced a higher level of itching and burning. That's when I went for allergy testing.
The only thing that has really helped is complete avoidance of citrus, gluten and nightshades.

Are you using pads, like Poise?? I'm very allergic to the many ingredients in them and have many friends who also are. My doctor didn't know about this, but friends told me they have the same reaction.
