Are there different types of erythromelalgia?

There are several types, including:

Primary erythromelalgia is isolated and not due to an underlying disease.

• Idiopathic erythromelalgia is the most common type and occurs for unknown reasons.
• Inherited erythromelalgia is due to gene mutations. The mutations, which affect pain signals, can be passed down in families.

Secondary erythromelalgia occurs when there is an underlying blood, neurological or immunologic condition. These include:

• Autoimmune diseases, such as lupus and multiple sclerosis.
• Essential thrombocythemia, a blood disorder that causes your body to produce too many platelets.
• Polycythemia vera.
• Raynaud's phenomenon.
• Thrombocytopenia.
• Neuropathy.
