Why is My Vagina Itchy Inside? A Comprehensive Guide
Quick Answer: Why is my vagina itchy inside? Internal vaginal itching is most often caused by a yeast infection, bacterial vaginosis, or sexually transmitted infections. Other possible causes include allergic reactions, hormonal changes, foreign objects, skin conditions, or even pinworms. If the itching lasts more than a few days, is severe, or comes with discharge, odor, or pain, see a doctor or other health care specialist for proper diagnosis and treatment.
What Is Vaginal Irritation?
Vaginal irritation refers to any discomfort, burning, stinging, or itching sensation that affects the vaginal canal or surrounding area. It can be external (around the vulva) or internal (deeper inside the vaginal canal). This irritation may be constant or come and go. Sometimes, it appears with other symptoms such as unusual discharge, pain, or odor.
The inside of the vagina is a delicate and self-cleaning environment. It contains healthy bacteria, maintains a naturally acidic pH, and produces secretions that help protect against infection. When something upsets this balance, it can lead to irritation, inflammation, and itching.1
Common Causes of Vaginal itching, Burning, and Irritation
Here are the most common reasons for internal vaginal itching.2
1. Yeast Infection (Candidiasis)
An overgrowth of Candida, a yeast that normally lives in the vagina, leads to inflammation. Antibiotics, high sugar diets, pregnancy, and a weakened immune system can disrupt the balance of bacteria and allow yeast to multiply.3
Symptoms:
- Itching inside the vagina
- Thick, white discharge (often described as “cottage cheese-like”)
- Redness, burning, or swelling
- Pain during sex or urination
2. Bacterial Vaginosis (BV)
An imbalance between good and harmful bacteria inside the vagina leads to BV.
Symptoms:
- Mild to moderate itching inside
- Thin, gray, or white discharge
- Strong “fishy” odor, especially after sex
Risk factors:
- Douching
- New or multiple sexual partners
- Smoking
3. Sexually Transmitted Infections (STIs)
Several STIs can cause internal vaginal itching.
Examples include:
- Trichomoniasis
- Chlamydia
- Gonorrhea
- Genital herpes
Symptoms vary but may include:
- Itching or burning
- Unusual discharge (greenish, yellow, or frothy)
- Sores, pain, or bleeding
If you suspect an STI, see a healthcare provider immediately. Prompt treatment protects you and your partners.
4. Allergic Reactions or Irritants
Sometimes, the cause is not an infection but exposure to something irritating.
Possible irritants include:
- Scented soaps, bubble baths, or detergents
- Lubricants or spermicides
- Latex condoms
- Fabric softeners or synthetic underwear
These products can disrupt the vagina’s natural balance and cause inflammation.
5. Hormonal Changes (e.g., Menopause)
Estrogen helps maintain vaginal tissue health. When estrogen levels drop—especially during perimenopause or menopause—the vaginal lining can become thin, dry, and easily irritated.
Symptoms of vaginal atrophy include:
- Itching or burning
- Dryness
- Discomfort during sex
- Increased risk of infections
This condition is common and treatable. Don’t suffer in silence.
6. Foreign Objects
Forgotten tampons or other objects inside the vagina can irritate the tissue and cause itching or discharge. This is more common than many realize.
Signs include:
- Strong, unpleasant odor
- Itching or pain
- Brown or bloody discharge
If you suspect this, seek medical help right away. Trying to remove it yourself may cause injury.
7. Skin Conditions
Certain skin conditions can affect the vaginal area and even extend inside.
Examples include:
- Lichen sclerosus
- Lichen planus
- Psoriasis
These conditions cause chronic inflammation and require a diagnosis from a doctor.
8. Pinworms
Though more common in children, pinworms can affect adult women. They can crawl into the vaginal area and cause itching.
Clues include:
- Intense nighttime itching
- Recent exposure to young children with pinworms
- Small white worms seen in stool or around the anus
Antiparasitic medications can eliminate the infection.
When to See a Doctor
You should not try to guess or self-diagnose internal vaginal itching, especially if:
- It lasts more than a few days
- You notice unusual discharge or odor
- There is pain or bleeding
- You have had recent unprotected sex
- Home remedies are not helping
Proper diagnosis may include a pelvic exam, lab tests, or swabs to identify infections.
What Not to Do
- Don’t douche. It disrupts the natural bacteria.
- Don’t scratch. Itching inside can worsen inflammation.
- Don’t use over-the-counter creams inside the vagina unless instructed. These are usually for external use only.
Treating Vaginal Itching
The best treatment for vaginal itching depends on the underlying cause.4 Here’s a breakdown of typical approaches:
- Yeast Infections: Over-the-counter (OTC) antifungal creams or suppositories usually clear up yeast infections. If your symptoms are severe or recurrent, your doctor may prescribe stronger medication.
- Bacterial Vaginosis: BV is treated with antibiotics, either oral pills or a vaginal gel.
- Irritants: Switching to unscented soaps, detergents, and hygiene products can help. Wear cotton underwear and avoid tight-fitting clothing.
- Skin Conditions: Your doctor might recommend medicated creams or ointments specific to the skin disorder.
- STIs: Treatment involves antibiotics or antiviral medications as prescribed by your doctor.
- Menopause: Using vaginal lubricants or moisturizers can offer relief from dryness. In some cases, your doctor may recommend estrogen therapy.
Home Remedies for Vaginal Itching
Alongside addressing the cause, simple home remedies might soothe itching:
- Yogurt: Unsweetened, plain yogurt with live cultures contains probiotics that might help restore the natural balance of vaginal bacteria. You can apply yogurt directly to the itchy area or insert it vaginally,
- Cool Compresses: Apply a cool compress to the affected area for a few minutes.
- Sitz Baths: Soaking in a warm (not hot) bath with plain water or adding baking soda or oatmeal can provide relief.
How to Prevent Vaginal Itching
- Wear breathable, cotton underwear
- Avoid scented feminine products
- Wipe front to back after using the toilet
- Change out of wet clothing promptly
- Practice safe sex
- Keep blood sugar under control if you have diabetes
