Differential Diagnosis for a 30-year-old Lady with Burning Sensation over Feet and Pedal Edema

  • Single most likely diagnosis:
    • Diabetic Neuropathy: This condition is a common cause of burning sensations in the feet, especially in individuals with poorly controlled diabetes. The pedal edema could be related to diabetes as well, either directly or through associated conditions like nephropathy leading to fluid retention.
  • Other Likely diagnoses:
    • Peripheral Artery Disease (PAD): Although less common in a 30-year-old, PAD can cause pain and burning sensations in the feet, especially during exercise, due to reduced blood flow. Edema might not be a direct symptom but could be related to associated conditions.
    • Vitamin B12 Deficiency: This deficiency can cause neuropathy, leading to burning sensations in the feet. Edema is not a direct symptom but could be related to other systemic effects of the deficiency.
    • Hypothyroidism: This condition can cause both neuropathic symptoms (like burning sensations in the feet) and edema (myxedema), making it a plausible diagnosis.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed):
    • Deep Vein Thrombosis (DVT): Although DVT typically presents with acute onset of swelling and pain, it's crucial not to miss this diagnosis due to its potential for severe complications like pulmonary embolism.
    • Sepsis or Infection: Infections, especially those involving the feet (like diabetic foot infections), can present with burning sensations and edema. Sepsis, a life-threatening condition, can arise from untreated infections.
  • Rare diagnoses:
    • Fabry Disease: A genetic disorder that can cause burning sensations in the feet due to neuropathy. It's rare but should be considered in younger patients with unexplained neuropathic pain and other systemic symptoms.
    • Erythromelalgia: A disorder characterized by burning pain, heat, and redness in the hands and feet. It can be primary or secondary to other conditions like myeloproliferative disorders.
    • Chronic Kidney Disease: Advanced kidney disease can cause neuropathy and edema, among other symptoms, due to fluid and electrolyte imbalances and the buildup of toxins.
