Why X-Rays Often Miss Heel Pain Causes

“Your X-ray is normal” is one of the most frustrating phrases patients with severe heel pain hear. Standard X-rays only visualize bone — they completely miss the soft tissue structures that cause the majority of heel pain. Understanding what X-rays can and cannot show helps patients understand why their pain is real even when imaging appears normal.

What X-Rays Miss

Plantar fasciitis — the most common cause of heel pain, affecting millions of Americans — is a soft tissue condition involving the fibrous band that runs along the bottom of the foot. The plantar fascia is invisible on X-ray. Fat pad atrophy (thinning of the heel’s natural cushioning), Baxter’s nerve entrapment (compression of a branch of the lateral plantar nerve at the heel), and tarsal tunnel syndrome (posterior tibial nerve compression) are all soft tissue conditions that appear entirely normal on standard X-ray.

What About Heel Spurs?

Heel spurs — calcified projections at the plantar fascia insertion — are often blamed as the cause of heel pain, but the research consistently shows they are poor predictors of symptoms. Approximately 25% of the general population has heel spurs on X-ray, and the majority have no heel pain. Conversely, many patients with severe plantar fasciitis have no spur at all. The spur is a marker of chronic fascial tension, not the pain generator. Removing spurs does not reliably resolve heel pain — addressing the underlying fascial and biomechanical factors does.

Diagnostic Ultrasound: The Next Step

Diagnostic musculoskeletal ultrasound is the ideal next imaging step for unexplained heel pain. It visualizes the plantar fascia in real time — measuring thickness (greater than 4mm suggests plantar fasciitis), identifying microtears, and assessing vascularity with Doppler imaging. It also visualizes Baxter’s nerve, identifies ganglionic cysts, and guides diagnostic and therapeutic injections with precision. At Balance Foot & Ankle, diagnostic ultrasound is available in-office for immediate assessment.

When MRI Is Indicated

MRI provides superior soft tissue resolution and is indicated when: stress fracture of the calcaneus is suspected (early stress fractures may be invisible on X-ray for 2-4 weeks), the diagnosis remains unclear after clinical examination and ultrasound, or surgical planning requires detailed characterization of anatomy. MRI can diagnose plantar fascia rupture, calcaneal stress fractures, bone marrow edema, and soft tissue masses that other modalities miss.

Getting Answers

A normal X-ray should be the beginning of the diagnostic process, not the end. At Balance Foot & Ankle in Howell or Bloomfield Township, our podiatrists combine clinical examination with in-office diagnostic ultrasound to identify the specific cause of heel pain — and target treatment precisely.

Heel Pain But Normal X-Ray? We Find the Real Cause

A normal X-ray doesnt mean nothing is wrong. Many causes of heel pain — plantar fasciitis, nerve entrapment, stress reactions, and bursitis — dont show on standard X-rays. Dr. Tom Biernacki uses ultrasound and advanced evaluation to find what X-rays miss.
