Hello
I have been researching your question and came up with the following article. It is a rare disorder, however considering you've had other things checked out by your doctor, it's worth reading about.
Erythromelalgia is a rare condition that primarily affects the feet and, less commonly, the hands (extremities). It is characterized by intense, burning pain of affected extremities, severe redness (erythema), and increased skin temperature that may be episodic or almost continuous in nature.
The specific underlying cause of erythromelalgia remains unknown. However, the condition is thought to result from vasomotor abnormalities or dysfunction in the normal narrowing (constriction) and widening (dilation) of the diameter (caliber) of certain blood vessels, leading to abnormalities of blood flow to the extremities. Erythromelalgia may be an isolated, primary condition or occur secondary to various underlying disorders. Primary erythromelalgia may appear to occur randomly for unknown reasons (sporadically) or may be familial, suggesting autosomal dominant inheritance.

Erythromelalgia is a condition affecting the extremely small blood vessels in the body (micro-circulation). Burning pain of red and warm hands and/or feet are the classical symptoms of erythromelalgia, the feet being predominantly involved. It can occur at any age, being reported in children as young as age five.
The cause is often unknown and the condition doesn't always 'develop into a worsening scenario'. The condition may be associated with underlying illness that can take time to become apparent and some doctors recommend ongoing surveillance of patients with erythromelalgia in order to detect any disorders as they develop. Treatment depends upon the severity of the symptoms and any associated conditions. Several case reports show response to aspirin and intravenous treatment with sodium nitroprusside and prostaglandins.
