Signs & symptoms

Symptoms of SFSN may include burning or shooting pain in the hands or feet, increased sensitivity to touch or temperature, numbness or tingling sensations, and muscle weakness.


Diagnosis of SFSN can be challenging as the symptoms can be similar to other conditions, and there are no specific tests for SFSN. Diagnosis usually involves a thorough medical history, physical examination, and nerve conduction studies. A skin biopsy may also be performed to examine the small sensory nerves.


Treatment for SFSN may depend on the underlying cause of the condition, but can include medications to relieve pain and reduce inflammation, such as gabapentin or pregabalin. Physical therapy may also be recommended to improve muscle strength and mobility.
