🦴 Possible Reasons for Pain in One Hip

​

Pain affecting only one hip often points to a localised mechanical, inflammatory, neurological, or referred cause. While degenerative joint disease is common, non-orthopaedic contributors are frequently overlooked.

Below are key possibilities to consider.

1. Ballooning or Distension of the Sigmoid Colon

Distension of the sigmoid colon may occur when chronic constipation, microbial imbalance, or parasitic burden leads to gas, pressure, and stagnation. Over time, increased intraluminal pressure can cause sections of the bowel wall to bulge outward, placing pressure on surrounding tissues.

In some individuals, chronic inflammatory or infectious processes in the pelvis may irritate nearby nerves, muscles, or connective tissue, potentially contributing to referred pain felt in one hip.
(This mechanism is still being explored in integrative medicine and should not replace medical evaluation.)

2. Osteoarthritis

The most common cause of hip pain. It develops when the cartilage cushioning the hip joint wears down, leading to stiffness, inflammation, reduced mobility, and pain—often worse with activity.

3. Bursitis

Inflammation of the hip bursae (fluid-filled cushioning sacs) can cause sharp or aching pain, especially when lying on the affected side or during repetitive movement.

4. Tendinitis

Overuse or strain of tendons around the hip—particularly the hip flexors or gluteal tendons—can lead to pain during walking, stair climbing, or rising from a seated position.

5. Hip Labral Tear

The labrum stabilises the hip joint. Tears—often from trauma or repetitive motion—may cause deep hip pain, clicking, catching, or instability.

6. Sciatica

Compression or irritation of the sciatic nerve (from disc herniation, piriformis syndrome, or spinal degeneration) may cause pain radiating into one hip and down the leg.

7. Sacroiliac (SI) Joint Dysfunction

Inflammation or misalignment of the SI joint can produce one-sided hip or buttock pain, often worsened by standing, walking, or transitioning between positions.

8. Iliotibial (IT) Band Syndrome

Tightness or inflammation of the IT band can cause pain along the outer hip, particularly in active individuals.

9. Infection or Inflammatory Disease

• Septic arthritis: A medical emergency marked by severe pain, fever, and restricted movement

• Rheumatoid arthritis: An autoimmune inflammatory condition that may affect the hip

10. Avascular Necrosis

Reduced blood supply to the femoral head can cause bone death and collapse, leading to progressive pain and joint dysfunction.

11. Muscle Strain or Weakness

Injury or imbalance of the hip flexors, gluteals, or hamstrings can cause unilateral hip pain, especially after exertion.

12. Leg Length Discrepancy

Structural or functional differences in leg length can overload one hip, leading to chronic strain and pain.

13. Tumours or Bone Lesions (Rare)

Although uncommon, masses in the pelvis or femur should be ruled out if pain is persistent, progressive, or unexplained.

14. Referred Pain

Pain perceived in the hip may originate from the lumbar spine, pelvis, abdomen, or bowel, highlighting the importance of a whole-body assessment.

🧠 Clinical Note

Accurate diagnosis requires a comprehensive assessment, including medical history, physical examination, and—where appropriate—imaging or laboratory investigations. Early identification of the true cause may prevent unnecessary progression or invasive intervention.

🌿 Functional Support Recommendations

• Systemic Enzyme Support

Natto-K-Serra (containing nattokinase and serrapeptase) may help support:

• Healthy inflammatory balance

• Breakdown of excess fibrin and mucus

• Circulatory and immune health

• Microbial & Tissue Support

Lysine-C may support immune defence and help create an environment less favourable for pathogenic overgrowth when used as part of a broader integrative approach.

• Foundational Strategies

• Support liver and colon function regularly

• Reduce sugar and refined starch intake (which may promote dysbiosis)

• Maintain adequate hydration

• Address diet, posture, movement, and gut health together
