Small fiber neuropathy is a type of neuropathy where the small nerves in your skin, which are responsible for sensing pain and temperature, are affected. People with this condition often feel pain or burning sensations, especially in their hands and feet. They might also have a hard time detecting changes in temperature or noticing acute sensations like the prick of a needle. Unlike other types of neuropathy, small fiber neuropathy doesn't usually cause weakness. It can be tricky to diagnose because routine nerve tests might not pick it up. Doctors often use a combination of skin biopsy tests, in-office examination, and blood work to help provide an accurate diagnosis. The treatment mainly focuses on managing symptoms and addressing any underlying conditions that might be causing it.
