Vaginal pain - Causes, Treatment & When to See a Doctor

What is Vaginal Pain?

Vaginal pain (vulvodynia or vestibulodynia when specifically referring to vulvar/vaginal opening pain) refers to discomfort, aching, soreness, burning, or sharp sensations occurring in or around the vagina. It may involve external genital structures (vulva), internal vaginal walls, or deeper pelvic tissues. Pain ranges from mild irritation to severe discomfort affecting daily activities and sexual health. Affecting people of all ages, it requires proper evaluation since it may signal underlying health conditions.

Common Causes

Multiple conditions can trigger vaginal pain. Common causes include:

• Vaginal Infections: Candida (yeast) infections, bacterial vaginosis (BV), and sexually transmitted infections (STIs) like herpes or trichomoniasis (CDC).
• Skin Conditions: Vulvar eczema, psoriasis, lichen sclerosus (Mayo Clinic), or allergic reactions to chemicals in soaps or lubricants.
• Anatomic Cysts/Abscesses: Bartholin's gland cysts or infected Skene's duct cysts.
• Vulvodynia: Chronic pain (≥3 months) without identifiable cause, affecting 8-10% of women (NIH).
• Atrophic Vaginitis: Hormone-related vaginal dryness and thinning, common after menopause (Cleveland Clinic).
• Pelvic Floor Dysfunction: Involuntary muscle spasms (vaginismus) causing entry pain (ACOG).
• Trauma: Surgical scars, childbirth injuries, or friction-related abrasions.
• Cancer: Vaginal/vulvar cancers (though rare), presenting as persistent soreness or lesions (ACS).
• Endometriosis: Lesions affecting vaginal/vulvar nerves.
• Urological Conditions: Interstitial cystitis causing referred vaginal pain.

Associated Symptoms

Vaginal pain often occurs alongside:

• Itching, redness, or swelling
• Abnormal discharge (thick, foul-smelling, discolored)
• Urinary symptoms (burning during urination)
• Pain during sexual intercourse (dyspareunia)
• Skin changes (lesions, ulcers, texture/thinning)
• Sensation of vaginal pressure or throbbing

When to See a Doctor

Consult a healthcare provider if you experience:

• Persistent pain lasting over 1–2 weeks
• Unidentifiable lumps or sores
• Blood in vaginal discharge
• Pain interfering with daily activities or sleep
• Symptoms persisting despite OTC treatments
• Increased bladder/bowel discomfort

Diagnosis

Diagnostic evaluation includes:

• Medical History: Symptom patterns, lubrication, hormonal status, sexual history.
• Physical Exam: Visual vulvar inspection; vaginal exam using speculum; pelvic floor muscle assessment.
• Lab Tests: Swab tests for infections (pH testing, cultures/KOH prep); PCR/NAAT for STIs.
• Imaging: Ultrasound or MRI for suspected cysts/deep lesions.
• Biopsy: For unexplained lesions/thickening (e.g., lichen sclerosus).

Treatment Options

Treatment depends on underlying causes:

Medical Treatments

• Infections: Antifungals (fluconazole), antibiotics (metronidazole), antivirals (acyclovir).
• Hormone Deficiencies: Topical estrogen creams/suppositories.
• Chronic Pain: Tricyclic antidepressants (amitriptyline), nerve pain agents (gabapentin).
• Skin Conditions: Steroid/immunosuppressive creams (clobetasol).
• Muscle Dysfunction: Pelvic floor physical therapy, trigger point therapy.

Home Care

• 💧 Use water-based lubricants during intercourse (avoid glycerin flavors).
