How is it diagnosed?

Small fiber neuropathy can be difficult to diagnose because its symptoms are similar to those of many other conditions. The most common way to diagnose small fiber neuropathy is by performing a nerve biopsy. This is a surgical procedure in which a tiny piece of your nerve is removed and examined under a microscope.

Other tests that may be used to diagnose small fiber neuropathy include:

• A physical exam can help your doctor identify any abnormalities in your hands and feet
• Blood tests, can help rule out other conditions that may be causing your symptoms
• Nerve conduction tests, can help measure the electrical activity in your nerves
• Skin biopsy, which involves removing a small piece of skin from your arm or leg to be examined under a microscope
