Iliac Crest Pain: Common Causes and Treatment Options

You’ve been feeling that nagging ache near your hip, right where your hand instinctively rests as you stand up—coincidentally, it’s the same spot that flares up after a long walk or an intense workout. Iliac crest pain isn’t just discomfort; it’s your body signaling something’s off, whether from weak core muscles, an old injury, or even overuse in growing teens. But what’s really behind it, and how can you fix it? The answers could surprise you.

Weak Core Muscles and Iliac Crest Pain

Weak core muscles could be the concealed reason behind your iliac crest pain. Whenever your core isn’t strong enough, it struggles with stabilizing the hips and maintaining proper spine alignment.

Without enough pelvis support, everyday movements—like bending or twisting—place extra strain on the iliac crest, leading to discomfort.

Weak core muscles shift strain to the iliac crest, turning simple movements into sources of pain. Strengthen to stabilize.

The positive aspect? Core strengthening exercises can help. By improving overall stability, you reduce muscle strain and ease the load on your pelvis.

Rehabilitation through physical therapy is another effective option, especially in case your pain persists.

Focus on movements that engage your deep abdominal muscles, since they’re key to preventing future issues.

A stronger core means better balance, less pain, and smoother movement—so don’t skip those planks and bridges!

Trauma and Fractures to the Iliac Crest

Should you have taken a hard fall or suffered a sports injury, you could be managing iliac crest pain from trauma or even a fracture. High-impact accidents can crack the bone, causing sharp pain, swelling, and bruising that worsens with movement.

To confirm a fracture, your doctor will probably order imaging tests like X-rays or CT scans. Treatment depends on severity—mild cases often heal with rest, ice, compression, and elevation (RICE).

Avoid activities that strain the area, and give your body time to recover. For serious fractures, surgery may be needed to stabilize the bone.

Listen to your body; pushing through pain slows healing. When discomfort persists, follow up with your healthcare provider to rule out complications. Initial diagnosis and proper care help you bounce back faster.

Iliac Apophysitis in Adolescents and Children

Growing pains aren’t always just a phase—if your active child or teen complains of soreness along the hip bone, iliac apophysitis could be the culprit. This overuse injury happens as repetitive physical activities strain the growth plate at the iliac crest, causing inflammation and localized pain.

Here’s what you need to know:

  1. Who’s at risk? Adolescents in sports like soccer or gymnastics, where running and jumping are frequent.
  2. Symptoms include tenderness at the hip bone, especially after activity, but it eases with rest.
  3. Diagnosis involves a physical exam, and sometimes imaging, to rule out fractures or muscle tears.
  4. Treatment approaches focus on rest, ice, and physical therapy to strengthen muscles and support healing.

Early action helps prevent long-term issues, so don’t ignore persistent discomfort.

Iliolumbar Syndrome and Ligament Inflammation

Should your child’s hip pain turn out to be more than just growing pains, you could contemplate what else could be causing discomfort in the same area.

Iliolumbar syndrome, involving inflammation of the iliolumbar ligament, could be the culprit. This ligament connects your lower spine to the pelvis, and at the time it’s strained—often from lifting, twisting, or weak core muscles—it can trigger sharp lower back pain and reduce pelvic stability.

You’ll notice stiffness or tenderness near the hip, sometimes spreading to the buttocks. Treatment options include rest, anti-inflammatory medications, and physical therapy to strengthen core muscles and improve flexibility.

Gentle stretches and targeted exercises can ease inflammation while restoring strength. In case pain lingers, a doctor could suggest injections for relief. Addressing it promptly helps prevent chronic issues.

Sacroiliac Joint Dysfunction and Referred Pain

Should you’ve ever felt a deep ache in your lower back that shoots into your buttocks or legs, sacroiliac joint dysfunction could be to blame.

This condition happens once the joint connecting your sacrum and ilium becomes inflamed or misaligned, causing pain near the iliac crest and beyond. Here’s what you should know:

  1. Causes: Aging, arthritis, pregnancy, or high-impact sports can stress the joint, leading to inflammation and referred pain.
  2. Symptoms: You could feel sharp or dull pain in your lower back, stiffness, or even tingling down your legs.
  3. Diagnosis: A doctor will check your medical history, perform exams, and can use X-rays or MRIs to confirm the issue.
  4. Treatment Options: Rest, physical therapy, or anti-inflammatory meds can help ease discomfort and strengthen lower back muscles.

If symptoms persist, don’t ignore them—early care makes a difference.

Rare Conditions: Bone Cancer and Iliac Crest Pain

A dull, persistent ache in your iliac crest that won’t fade—even after rest—could signal something more serious than muscle strain or joint inflammation.

Bone cancer, though rare, could be the cause. Types like osteosarcoma and Ewing’s sarcoma often target younger individuals, causing iliac crest pain alongside swelling or fractures.

Diagnosis starts with imaging studies—X-rays, CT scans, or MRIs—followed by a biopsy to confirm.

Treatment options vary: surgery removes tumors, chemotherapy targets cancer cells, and radiation therapy shrinks growths.

Catching it sooner improves results, so don’t ignore ongoing discomfort. While scary, modern treatments offer hope.

Should your pain linger or worsen, see a doctor—they’ll rule out rare causes and help you find relief.

Stay proactive about your health.
