What Can Be Mistaken for Plantar Fasciitis?
If you wake up with a sharp pain in your heel that makes the first few steps of the day feel impossible, you might assume it’s plantar fasciitis. It’s one of the most common causes of heel pain, especially among active individuals, runners, and people who spend long hours on their feet.
However, not all heel pain is caused by plantar fasciitis. Several other foot and ankle conditions can cause similar discomfort, and understanding the difference is key to getting the right treatment. Read on as Orlin & Cohen physical therapist Jamie Misegades, DPT, explains the most common conditions mistaken for plantar fasciitis and how to tell them apart.
Key Differences Between Plantar Fasciitis and Other Heel Pain
There are some important distinctions between plantar fasciitis and other heel pain:
- Location: Plantar fasciitis pain is usually on the bottom of the heel, especially near the arch. Achilles tendinitis and bursitis affect the back of the heel.
- Timing: Plantar fasciitis is most painful first thing in the morning or after sitting, while stress fractures and tendinitis hurt more after activity.
- Sensation: Burning, tingling, or numbness suggests a nerve-related condition, such as tarsal tunnel syndrome.
These symptoms can be subtle; if you’re experiencing any of them, it is important to have your symptoms evaluated by a foot and ankle specialist for an accurate diagnosis.
When Heel Pain Isn’t Plantar Fasciitis
Heel spurs
Heel spurs are small, bony growths that form on the underside of the heel bones, often after repeated stress or inflammation in the surrounding tissue. They frequently develop alongside plantar fasciitis, which is why they’re so easily confused.
Like plantar fasciitis, heel spurs can cause stabbing heel pain, especially when you stand up after resting. Not everyone with heel spurs feels pain; many people only discover them through imaging. The main difference is that pain from heel spurs tends to be localized under the heel, while plantar fasciitis usually spreads across the arch or the inner heel.
Achilles tendinitis
The Achilles tendon connects your calf muscles to your heel bone, and when it becomes irritated or inflamed, it can lead to Achilles tendonitis. Pain from Achilles tendinitis is typically felt in the back of the heel or just above it, not the bottom of the foot like plantar fasciitis. It also tends to flare up during or after physical activity rather than first thing in the morning.
Tarsal tunnel syndrome
Tarsal tunnel syndrome occurs when the posterior tibial nerve, located near the inside of your ankle, becomes compressed. This typically results in burning, tingling, or shooting pain that radiates from the heel to the arch, and sometimes to the toes. Unlike the pinpoint pain of plantar fasciitis, tarsal tunnel syndrome often causes numbness or a “pins and needles” sensation.
Stress fractures
A stress fracture is a tiny crack in the bone caused by repetitive impact or overuse. It is common among athletes, runners, and people who suddenly increase their activity level. Stress fractures in the heel can mimic plantar fasciitis pain, but there are subtle differences. Stress fracture pain tends to worsen with activity and may cause tenderness or swelling directly over the affected area. In contrast, plantar fasciitis pain usually improves once you start moving.
Nerve entrapment
When nerves in the foot become compressed or irritated, they can cause pain similar to plantar fasciitis. Nerve entrapment often produces sharp, burning, or electric-like sensations that may travel up the leg. If your heel pain feels more like tingling or numbness, or radiates rather than staying localized, it could be a nerve issue rather than inflammation or plantar fasciitis.
Effective Treatment Options for Heel Pain
Stretching and strengthening exercises
Gentle stretching of the calves, Achilles tendon, and plantar fascia can help relieve tension and improve flexibility. Strengthening exercises for the foot and ankle muscles also support better stability and long-term pain relief.
Custom orthotics
Custom orthotic inserts provide extra arch support and correct foot mechanics, reducing strain on the heel and plantar fascia. Over-the-counter insoles can help in mild cases, but custom orthotics or orthopedic shoes are designed for your foot’s unique structure for optimal results.
Preventing Future Foot and Heel Problems
Prevention starts with good foot habits. Wear supportive shoes, replace old sneakers regularly, and avoid walking barefoot on hard surfaces for long periods. Incorporating foot stretches before and after activity, maintaining a healthy weight, and listening to early signs of discomfort can also help prevent recurring pain.
