Differential Diagnosis for Pain at the Bottom of the Toe
Single Most Likely Diagnosis
- Morton's Neuroma: This condition is characterized by a benign growth of nerve tissue in the ball of the foot, commonly between the third and fourth toes, causing pain, numbness, and tingling. It's a common cause of toe pain and fits the described location.
Other Likely Diagnoses
- Ingrown Toenail: This occurs when the nail grows into the surrounding skin, causing pain, redness, and swelling. It's a frequent issue that can cause significant discomfort at the bottom or sides of the toe.
- Subungual Hematoma: Blood accumulation under the nail due to injury can cause pain and pressure at the bottom of the toe, especially if the hematoma is large.
- Toe Fracture: A fracture of one of the toe bones (phalanges) can cause pain at the bottom of the toe, especially if the fracture involves the distal phalanx.
- Bursitis: Inflammation of the bursae (fluid-filled sacs) at the base of the toes can cause pain and swelling in the area.
Do Not Miss Diagnoses
- Osteomyelitis: A bone infection that can cause severe pain, redness, and swelling. While less common, missing this diagnosis can lead to serious complications, including the need for amputation.
- Gout or Pseudogout: These are forms of arthritis that can cause sudden, severe pain in the toes, often accompanied by redness and swelling. Missing these diagnoses can lead to prolonged suffering and potential joint damage.
- Diabetic Neuropathy: Nerve damage due to diabetes can cause a variety of symptoms, including pain, numbness, and tingling in the feet and toes. Early diagnosis is crucial for managing the condition and preventing further complications.
Rare Diagnoses
- Glucoma of the Toe: A rare condition where a benign tumor forms on the nerve endings, causing pain and sensitivity.
- Erythromelalgia: A disorder that causes burning pain, heat, and redness in the hands and feet, which can sometimes be localized to the toes.
- Subungual Exostosis: A rare bone growth under the nail that can cause pain and discomfort, especially if it presses on the surrounding tissue.
