Vaginal or vulvar pain that flares up when you sit down usually comes from one of a handful causes: tight pelvic floor muscles, nerve irritation, a cyst near the vaginal opening, or a chronic pain condition called vulvodynia. Sitting compresses the tissues between your pelvic bones, and when any of those structures are inflamed, tense, or irritated, that pressure becomes painful. About 16% of women experience chronic vulvar pain at some point, so this is far more common than most people realize.
Tight Pelvic Floor Muscles
The pelvic floor is a hammock of muscles stretching from your pubic bone in front to your tailbone in back, anchored to the sit bones on each side. When these muscles get stuck in a state of constant contraction, a condition called hypertonic pelvic floor, they can cause pain in the vaginal area, lower back, and hips. Sitting puts direct pressure on muscles that are already in spasm, which is why the discomfort spikes in a chair and eases when you stand or lie down.
Prolonged sitting itself can actually contribute to the problem. Spending hours at a desk, poor posture, or even an uneven walking pattern can trigger or worsen pelvic floor tension over time. The pain often shows up not just when sitting but also during bowel movements, sex, or tampon use. If this sounds familiar, the underlying issue is muscular, and it responds well to specific stretching and relaxation techniques (more on those below).
Pudendal Nerve Irritation
The pudendal nerve runs through your pelvis and supplies sensation to the vulva, perineum, and rectal area. When this nerve gets compressed or irritated, a condition called pudendal neuralgia, the hallmark symptom is pain that worsens with sitting and improves when you stand or lie down. The pain can feel like burning, stabbing, or an electric sensation in the genital area, buttocks, or perineum.
The reason sitting is the trigger is straightforward: the nerve passes through a narrow canal near the sit bones, and sitting compresses it directly. Cycling, horseback riding, and chronic constipation are common contributing factors. Diagnosis typically involves a physical exam where a provider applies pressure along the nerve’s path, and sometimes a nerve block injection. If numbing the nerve eliminates the pain, that confirms the source.
Bartholin’s Cyst or Abscess
The Bartholin’s glands sit on either side of the vaginal opening and help with lubrication. When one of these glands gets blocked, fluid backs up and forms a cyst. A small cyst may feel like a painless pea-sized lump on one side. But if it grows or becomes infected, it can swell into a tender, painful mass that makes sitting and walking genuinely uncomfortable.
An infected Bartholin’s cyst can progress from mild tenderness to a full abscess within days. You’ll typically notice a lump on just one side of the vaginal opening, along with warmth, redness, and increasing pain. This is one of the more straightforward causes to identify because you can often feel or see the swelling yourself.
Vulvodynia and Vestibulodynia
Vulvodynia is chronic vulvar pain lasting three months or longer without an identifiable infection or skin condition to explain it. The pain can be constant or triggered by pressure, and it often makes prolonged sitting feel unbearable. The exact cause isn’t fully understood, but nerve injury or irritation in the vulvar tissue is thought to play a role.
A specific subtype called vestibulodynia affects the tissue right at the vaginal entrance (the vestibule). This is the most common form of localized vulvodynia, and it’s typically provoked, meaning the pain flares when something applies pressure to that area. Sitting on a hard surface, inserting a tampon, or a pelvic exam can all trigger it. The pain is often described as burning, stinging, or raw soreness concentrated at the vaginal opening rather than deep inside.
How to Tell These Apart
The pattern of your pain offers useful clues:
- Pain improves immediately when standing or lying down: This points toward pudendal nerve irritation or pelvic floor muscle tension, since removing pressure from the nerve or muscles brings quick relief.
- A visible or palpable lump on one side: A Bartholin’s cyst or abscess is the most likely explanation, especially if it developed over days and feels warm or tender.
- Burning or rawness at the vaginal entrance: Vestibulodynia tends to produce this specific sensation, particularly when the tissue is touched or pressed.
- Deep, aching pelvic pressure that also shows up during bowel movements or sex: Hypertonic pelvic floor muscles often cause this broader pattern of symptoms.
- Pain accompanied by fever, unusual discharge, or rapidly increasing swelling: These signs suggest infection and need prompt medical attention.
Sitting Modifications That Help
Regardless of the underlying cause, the way you sit can make a significant difference. A donut-shaped cushion (sometimes called a coccyx cushion) redistributes your weight away from the center of your pelvis and onto your thighs, reducing direct pressure on the vulva and perineum. This is one of the first recommendations for pudendal neuralgia and is useful for most causes of sitting-related vulvar pain.
Beyond the cushion, try to avoid sitting on hard, flat surfaces for extended periods. Soft chairs are better than wooden ones. Standing desks or sit-stand workstations let you alternate positions throughout the day. When you do sit, keep your feet flat on the floor and avoid crossing your legs, which can tilt the pelvis and increase pressure on one side.
Stretches for Pelvic Floor Tension
If muscle tightness is contributing to your pain, the goal is to teach those muscles to relax rather than strengthen them further. Kegel exercises, which tighten the pelvic floor, can actually make this kind of pain worse. Instead, focus on lengthening and releasing.
A widened child’s pose is one of the most effective positions. Kneel on the floor, bring your hips back toward your heels, and let your knees fall wide apart. Hold for 10 to 30 seconds, breathing slowly, and repeat five times. The cobra stretch also helps: lie face down and gently push your chest off the floor using your elbows or hands, holding for 15 to 30 seconds, five repetitions.
Diaphragmatic breathing targets pelvic tension directly. Lie down comfortably with your hands on your lower ribs. Inhale through your nose for five seconds, feeling your ribcage expand, and consciously relax your pelvic floor as you breathe in. Exhale through your mouth for five seconds. Repeat for 10 full breaths, rest, then do another set. The key is to visualize the pelvic floor softening and releasing with each inhale. Over time, this trains the muscles to let go of the tension they’re holding.
What Treatment Looks Like
For pelvic floor dysfunction, the most effective treatment is working with a pelvic floor physical therapist. These specialists use hands-on techniques to release tight muscles and teach you how to keep them from seizing up again. Most people notice meaningful improvement within several weeks of consistent sessions and home exercises.
Pudendal neuralgia treatment usually starts conservatively with physical therapy, nerve-calming medications, and sitting modifications. If those don’t provide enough relief, nerve block injections can interrupt the pain cycle. For Bartholin’s cysts, small ones may resolve on their own with warm soaks (sitz baths), while larger or infected ones sometimes need to be drained.
Vulvodynia can be more challenging to treat because the cause is less clear, but most people find relief through a combination of pelvic floor therapy, topical treatments applied to the vulvar tissue, and strategies to calm overactive nerve signals. The condition is manageable, though it often takes some patience to find the right combination of approaches.
