SI Joint Pain From Trauma Leading to Pudendal Nerve & Pelvic Floor Pain?

Let’s get straight to it—SI joint pain caused by trauma isn’t just “lower back pain.” For many people, it can trigger a cascade of symptoms, including pudendal nerve pain and pelvic floor dysfunction that can disrupt daily life.

If you’ve been dealing with SI joint injury, and now you're experiencing weird pelvic sensations, nerve irritation, or muscle tightness—this post is for you.

You’re not imagining things.
There’s a real connection between SI joint dysfunction, pudendal neuralgia, and pelvic floor pain—and this post will break it all down and give you actionable insights to start finding relief.

The sacroiliac (SI) joints connect the base of your spine to your pelvis. These joints are strong and stable, but they can be injured during trauma—think falls, car accidents, sports injuries, or even childbirth.

When this joint is damaged or inflamed, it can cause:

• Lower back pain

• Buttock pain

• Discomfort while sitting, walking, or climbing stairs

• Sensations that mimic sciatica or nerve issues

Here’s the kicker: when your SI joint becomes unstable or inflamed, it can affect the muscles, nerves, and tissues in the surrounding pelvic area, including the pudendal nerve.

Let’s connect the dots. The pudendal nerve runs through the pelvis and provides sensation and motor control to the genitals, perineum, and parts of the pelvic floor.

When there’s pelvic misalignment—often caused by SI joint instability—this nerve can become compressed or irritated, leading to:

• Burning or tingling sensations in the pelvic area

• Pressure or numbness while sitting

• Pain during movement or after prolonged sitting/standing

• Pelvic floor tension or dysfunction

This is often referred to as pudendal neuralgia, and it’s more common than most people think—especially after trauma to the pelvis or lower back.

If you’ve had a traumatic injury and now have SI joint pain, be on the lookout for these symptoms that may signal pudendal nerve irritation or pelvic floor issues:

• Persistent pelvic or perineal pain

• Pain that worsens when sitting but eases when standing or lying down

• Muscle tightness or spasms in the lower abdomen or inner thighs

• Pain with urination, bowel movements, or sexual activity

These symptoms can be misdiagnosed or ignored—especially if a practitioner is only looking at the lower back and not the pelvic region as a whole.

There’s no one-size-fits-all solution, but here are evidence-based and real-world approaches that have helped many people deal with SI joint dysfunction and related nerve pain.

1. Pelvic Floor Physical Therapy (PT)

One of the most effective treatments is working with a physical therapist who specializes in the pelvic floor and SI joint stability. These professionals can help with:

• Manual therapy to release tight muscles

• Stabilization exercises to support the SI joint

• Postural retraining to reduce nerve compression

• Pelvic floor relaxation techniques

Search tip: Look for therapists trained in pelvic health and pudendal neuralgia treatment.

2. SI Joint Stabilization Exercises

Strengthening the core and hip muscles can help reduce stress on the SI joint and improve pelvic alignment. Focus on:

• Transverse abdominis engagement (deep core)

• Glute activation (especially glute medius)

• Gentle mobility work for hips and pelvis

Caution: Avoid high-impact movements or exercises that cause pain or nerve flare-ups.

3. Targeted Stretching and Mobility

While strengthening is key, releasing tension in certain muscle groups can relieve pressure on the pudendal nerve and help the pelvic floor function properly.

Key areas to stretch and mobilize:

• Piriformis and hip rotators

• Hip flexors

• Adductors (inner thighs)

• Lower back and hamstrings

Remember: It’s not about over-stretching—it’s about balance.

4. Anti-Inflammatory Support (Diet + Hydration)

Chronic pain and nerve irritation are often fueled by inflammation. Support your healing with:

• A whole food, anti-inflammatory diet (think omega-3s, turmeric, leafy greens)

• Magnesium for muscle relaxation

• Hydration to keep tissues flexible and support healing

5. Stress Management + Breathwork

Stress increases muscle tension—especially in the pelvic floor—and can worsen nerve pain.

Daily practices like breathwork, mindfulness, or even gentle movement (e.g., yoga, tai chi) can help reset the nervous system and support recovery.

If you’re dealing with SI joint pain from trauma, and now have pudendal nerve symptoms or pelvic floor dysfunction, know this:

• It’s a real physical issue, not just “in your head.”

• Getting the right help—especially from pelvic health professionals—can make a huge difference.

• Healing is possible, but it often requires a comprehensive approach, not just pills or rest.
