Differential Diagnosis for Intermittent Burning Sensation at Lateral Nail of Great Toe
- Single Most Likely Diagnosis
- Ingrown toenail: This condition is characterized by the nail growing into the surrounding skin, causing pain, swelling, and sometimes infection. The intermittent burning sensation at the lateral nail of the great toe is a common symptom of an ingrown toenail, especially if the nail is pressing into the skin.
- Other Likely Diagnoses
- Onychomycosis (fungal infection of the nail): Fungal infections can cause changes in the nail's texture, color, and shape, and may lead to a burning sensation due to the infection and subsequent inflammation.
- Neuroma (Morton's neuroma): Although more commonly associated with the space between the third and fourth toes, a neuroma can occasionally occur in the area of the great toe, causing burning pain.
- Bursitis: Inflammation of the bursae around the joints or under the skin near the nail can cause pain and a burning sensation.
- Do Not Miss Diagnoses
- Osteomyelitis (bone infection): Although less common, an infection of the bone in the toe can cause severe pain and a burning sensation. It's crucial to consider this diagnosis, especially if there's a history of trauma or signs of infection.
- Diabetic neuropathy: Individuals with diabetes may experience neuropathic pain, including burning sensations in the feet, due to nerve damage. This condition requires prompt management to prevent further complications.
- Gout: Acute gouty arthritis can cause intense pain and burning sensations in the affected joint, most commonly the base of the big toe.
- Rare Diagnoses
- Erythromelalgia: A rare disorder characterized by burning pain, heat, and redness in the hands and feet. It can be primary or secondary to other conditions.
- Complex regional pain syndrome (CRPS): A chronic pain condition that can cause burning sensations, among other symptoms, usually after an injury or trauma.
- Peripheral artery disease (PAD): Reduced blood flow to the feet can cause pain, burning sensations, and other symptoms, especially during walking or exercise.
