Foot and Ankle Bursitis: Causes Locations Symptoms and Treatment Options

Quick answer: Treatment for foot ankle bursitis causes locations symptoms treatment follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

What Is Bursitis?

A bursa is a fluid-filled sac that cushions and lubricates areas where tendons, ligaments, skin, or muscles slide over bony prominences. The foot and ankle contain several anatomically defined bursae — the retrocalcaneal bursa behind the heel, the subcutaneous calcaneal bursa between the skin and Achilles tendon, the metatarsal bursae between the metatarsal heads, and the MTP joint bursae at the base of each toe. When these bursae become inflamed from direct pressure, repetitive friction, or underlying inflammatory arthritis, they fill with excess fluid and cause localized pain and swelling.

Common Bursitis Locations in the Foot

Retrocalcaneal Bursitis

The retrocalcaneal bursa lies between the posterior-superior calcaneus and the Achilles tendon insertion. Inflammation of this bursa — retrocalcaneal bursitis — causes deep posterior heel pain that is worsened by shoe pressure at the heel counter and by activities that load the Achilles tendon. It frequently co-exists with Haglund deformity (posterosuperior calcaneal bony prominence) and insertional Achilles tendinopathy, creating the posterior heel pain triad. Conservative treatment with heel lift, footwear modification, physical therapy, and corticosteroid injection resolves most cases. Refractory bursitis may require surgical bursectomy combined with calcaneal exostectomy.

Subcutaneous Calcaneal Bursitis

The subcutaneous bursa lies between the skin and the Achilles tendon at the heel. Direct friction from rigid-backed footwear creates chronic irritation and bursal swelling — the hallmark of the “pump bump” superficial component. This bursa is visibly swollen and tender to touch at the most posterior aspect of the heel. Open-backed shoes eliminate the irritating pressure and allow the superficial bursitis to resolve.

Metatarsal Bursitis

Small bursae between the metatarsal heads become inflamed in patients with metatarsalgia — forefoot pain from excessive plantar pressure. Hammertoe deformity, a long second metatarsal, and high-heeled footwear all concentrate forefoot pressure and provoke metatarsal bursitis. The inflamed bursa creates a soft, compressible lump between the metatarsal heads that may be confused with Morton neuroma on clinical examination. Ultrasound distinguishes bursitis from neuroma effectively. Metatarsal pads, wider footwear, and corticosteroid injection manage most cases successfully.

First MTP Joint Bursitis (Bunion Bursa)

The most clinically recognized foot bursa is the one that forms over the medial aspect of the bunion deformity — the bursa between the medial metatarsal head prominence and the overlying skin. This bursa forms in response to chronic shoe friction against the bunion bump and can become acutely inflamed (septic bursitis) if the overlying skin breaks down and allows bacterial entry. Acute septic bursitis requires antibiotic treatment and aspiration or surgical drainage. Chronic aseptic bunion bursitis is managed with wide footwear and, when necessary, bunionectomy to eliminate the bony prominence.

Inflammatory Arthritis and Bursitis

Rheumatoid arthritis, gout, and psoriatic arthritis frequently cause bursitis as part of their systemic inflammatory manifestation. Bursitis in these conditions is best managed by treating the underlying disease with systemic therapy in coordination with rheumatology. Local aspiration and corticosteroid injection provide symptom relief during flares while systemic treatment is optimized.

Diagnosis and Treatment

Ultrasound is the preferred imaging for foot and ankle bursitis — it accurately identifies bursal fluid, measures bursal size, and guides aspiration in real time. MRI provides additional soft tissue detail when complex bursitis or concomitant tendon pathology is suspected. Aspiration removes painful fluid and provides rapid relief. Corticosteroid injection into the bursa after aspiration reduces inflammation and decreases recurrence rates. Surgical bursectomy is reserved for refractory cases. Contact Balance Foot & Ankle for evaluation of any painful foot lump or localized swelling.
