I think you should look into erythromelalgia ... similar appearance on the skin, and the burning.
Taking adequate magnesium containing foods or supplements often stop these temporary reddening episodes.

Dr. Jay Cohen MD had this and fixed his own with magnesium.

Also I wonder what antibiotics you used when you had your infections in the toes? Ciprofloxacin or Levofloxacin? These drugs can cause nerve damage. Flagyl (metronidazole) and Zyvox also cause nerve damage.
