Why Would Plantar Fasciitis Hurt at Night?

Classic plantar fasciitis causes pain with the first steps in the morning (post-static dyskinesia) that typically improves after walking for a few minutes. Pain at night — while you’re resting and not bearing weight — is less typical for standard plantar fasciitis and should prompt closer evaluation.

At Balance Foot & Ankle in Howell and Bloomfield Township, Michigan, nighttime heel pain gets our attention because it can indicate conditions that require different or more urgent treatment.

Why the Classic “Morning Pain” Pattern Occurs

During sleep, the foot rests in a plantarflexed (toes-down) position, allowing the plantar fascia to contract and partially shorten. The first steps of the day suddenly stretch this shortened, inflamed tissue — producing the characteristic sharp first-step pain. As you walk and the fascia warms up and stretches, the pain eases. This is the textbook pattern.

Causes of Heel Pain at Night or at Rest

1. Severe, Acute Plantar Fasciitis

In cases of significant acute inflammation, the heel may throb or ache at rest — even at night. This is typically associated with significant swelling, tenderness to even light touch, and an overall more inflamed presentation than the classic intermittent first-step pain. Aggressive ice, anti-inflammatories, and rest are the mainstay; night splints maintain a stretch on the fascia overnight to reduce morning pain.

2. Tarsal Tunnel Syndrome

Compression of the posterior tibial nerve in the tarsal tunnel can cause burning, tingling, and aching at the heel and arch — including at rest and at night. Unlike plantar fasciitis, it has a neurological quality (burning, electric) and may be reproduced by tapping over the inner ankle (Tinel’s sign). It can coexist with plantar fasciitis (“double crush” phenomenon).

3. Heel Stress Fracture

A stress fracture of the calcaneus (heel bone) causes deep, aching heel pain that can be present at rest and is significantly worsened by any weight-bearing. Unlike plantar fasciitis, the pain is bone-deep and doesn’t ease with walking. Tenderness is elicited by squeezing the heel from both sides (medial-lateral squeeze test). MRI or bone scan confirms. Common in runners who dramatically increase mileage.

4. Inflammatory Arthritis (Enthesitis)

Seronegative spondyloarthropathies — including ankylosing spondylitis, psoriatic arthritis, and reactive arthritis — cause enthesitis (inflammation at the site where tendons and ligaments attach to bone). Heel pain from enthesitis is characteristically worse at rest and at night — the opposite of mechanical plantar fasciitis. Associated with low back pain, morning stiffness lasting more than 1 hour, eye inflammation (uveitis), or skin/nail changes (psoriasis). Requires rheumatology evaluation.

5. Nerve Pain (Peripheral Neuropathy)

Diabetic peripheral neuropathy commonly causes burning, tingling, and aching in the feet — including the heels — that is often worse at rest and at night. The classic description is burning feet at night that improves with getting up and walking. A comprehensive diabetic foot exam and neurological evaluation is essential.

6. Baxter’s Nerve Entrapment

The first branch of the lateral plantar nerve (Baxter’s nerve) can be compressed between the abductor hallucis muscle and the plantar fascia, causing medial heel pain that can persist at rest. Often coexists with plantar fasciitis. Diagnosed by location of tenderness (slightly more medial and deep than typical PF) and confirmed with MRI showing denervation of the abductor digiti minimi muscle.

Night Splints for Plantar Fasciitis

Even in classic plantar fasciitis without true nighttime pain, night splints are an effective treatment. By holding the foot in neutral dorsiflexion overnight, they maintain a stretch on the plantar fascia during sleep — preventing the contracture that causes first-step pain in the morning. Studies show they reduce morning pain by 50–80% in motivated patients. Compliance is the main challenge; the splints feel awkward initially but most patients adjust within a week.

When Nighttime Heel Pain Needs Urgent Evaluation

See a podiatrist promptly if your heel pain:

• Is primarily at rest or at night rather than with first steps
• Is deep and bone-like rather than soft tissue aching
• Is accompanied by fever, swelling, or redness
• Is getting progressively worse despite rest
• Is associated with low back stiffness, skin rashes, or eye problems
• Is in both heels symmetrically

At Balance Foot & Ankle, we take a thorough history to differentiate mechanical plantar fasciitis from the conditions above, and order appropriate imaging when the pattern doesn’t fit. The right diagnosis means the right treatment — and faster recovery.
