What are the treatment options for foot pain?

Treatment of Foot Pain

Start with conservative management including regular calf and plantar fascia stretching exercises (3-5 times daily), over-the-counter arch supports or heel cushions, NSAIDs for pain relief, activity modification, and proper footwear—continuing this regimen for 6 weeks before considering specialist referral. 1

Initial Conservative Management (First 6 Weeks)

Patient-Directed Measures

• Perform regular calf-muscle and plantar fascia stretching exercises 3-5 times daily, which are at least as effective as NSAIDs or steroid injections for plantar fasciitis 1, 2
• Apply ice through a wet towel for 10-minute periods to reduce inflammation 1
• Use over-the-counter heel cushions and arch supports 1, 3
• Avoid flat shoes and barefoot walking 1, 3
• Modify activities that worsen pain 1, 4
• Consider weight loss if indicated to reduce pressure on the foot 1, 3

Medical Interventions

• NSAIDs (such as naproxen) for pain relief and inflammation reduction 1, 3, 5
• Padding and strapping of the foot for additional support 1
• Proper footwear with adequate arch support and cushioning 1, 3

Imaging Considerations

• Conventional radiography is the first imaging study for chronic foot pain of unknown etiology, useful to distinguish among different causes and assess stress fractures, coalitions, and forefoot pathology 6
• Advanced imaging (ultrasound or MRI) is reserved for unclear cases or preoperative evaluation 6, 3, 4

If No Improvement After 6 Weeks

Refer to a podiatric foot and ankle surgeon while continuing initial treatments 1, 3

Additional Interventions

• Customized orthotic devices (though these have moderate benefit only in the medium term of 7-12 weeks, with no clear advantage over prefabricated orthotics) 1
• Night splinting 1, 3, 4
• Limited corticosteroid injections for plantar fasciitis (but avoid near the Achilles tendon due to risk of tendon rupture) 1, 3, 7
• Consider casting or fixed-ankle walker-type device 1

If No Improvement After 2-3 Months

Continue conservative measures and consider:

• Cast immobilization if not previously used 1
• Extracorporeal shock wave therapy 1, 7, 4
• Surgical options (plantar fasciotomy) 1, 7, 4
• Exploring alternative diagnoses 1

Specific Conditions

Plantar Fasciitis

• Presents with pain at the medial plantar aspect of the heel, worst with first steps in the morning 3, 4
• Stretching and foot orthotics are first-line therapy, followed by extracorporeal shockwave therapy, corticosteroid injection, or platelet-rich plasma injection 7
• Approximately 44% of patients continue to have pain 15 years after diagnosis, though 90% improve with conservative techniques 7, 4

Achilles Tendinopathy

• Midportion Achilles tendinopathy presents with pain approximately 2-6 cm proximal to the Achilles insertion 7
• Primary treatment involves eccentric strengthening exercises, with extracorporeal shockwave therapy as an option 7
• Insertional Achilles tendinopathy is managed with calf-muscle stretching, cryotherapy, and activity modification 3

Morton Neuroma

• Characterized by burning pain in the ball of the foot with numbness or burning radiating to the third and fourth toes 7
• First-line therapy consists of reducing activities that cause pain, orthotics, and interdigital corticosteroid injection 7
• Approximately 30% of patients may not respond to conservative treatment 7

Haglund's Deformity with Bursitis

• Presents as acute pain and inflammation lateral to the Achilles tendon with visible posterior lateral prominence 3
• Managed with open-backed shoes, orthoses, and accommodative padding 3

Critical Caveats

• Avoid corticosteroid injections near the Achilles tendon due to risk of tendon rupture 1, 3
• Avoid complete immobilization to prevent muscular atrophy and deconditioning 3
• Rule out other causes of heel pain including neurologic conditions, stress fractures, or systemic inflammatory diseases when standard treatments fail 3
• Consider evaluation for underlying rheumatic disease in patients with multiple symptomatic tendons 3

Special Populations: Diabetic Foot Care

For patients with diabetes experiencing foot pain:

• Annual comprehensive foot examination to identify risk factors for ulcers and amputations, including inspection and assessment of foot pulses 6
• Patients with insensate feet, foot deformities, and ulcers should have feet examined at every visit 6
• Refer patients who smoke or have loss of protective sensation, structural abnormalities, or history of prior lower-extremity complications to foot care specialists 6
• For diabetic peripheral neuropathy pain, consider pregabalin, duloxetine, gabapentin, or tricyclic antidepressants (amitriptyline), though none affords complete relief 6

Expected Outcomes

Most patients respond to conservative treatment within 6-8 weeks 1
