Get Small Fiber Neuropathy Treatment Online

Small fiber neuropathy (SFN) is a condition in which the small nerve fibers responsible for pain, temperature sensation, and autonomic functions are damaged. This leads to symptoms such as burning or stinging pain, tingling, hypersensitivity to touch, and sometimes autonomic problems like abnormal sweating or heart rate changes.

Diagnosis often involves a combination of clinical history, neurological examination, and a skin punch biopsy to count intraepidermal nerve fiber density. Quantitative sensory testing and autonomic function tests may also be used. Some patients require blood work to identify underlying causes such as diabetes, autoimmune conditions, or vitamin deficiencies.

Common causes include diabetes or prediabetes, autoimmune diseases (such as Sjogren syndrome or lupus), genetic mutations (such as SCN9A or SCN10A variants), vitamin deficiencies (especially B12), thyroid disorders, and certain infections. In some cases no cause is found and the condition is called idiopathic SFN.

There is currently no universal cure, but treatment focuses on two goals: addressing any underlying cause to slow or halt progression, and managing symptoms to reduce pain and improve daily function. Many patients achieve significant relief with the right combination of therapies.

Treatments commonly used for neuropathic pain in SFN include topical agents such as lidocaine patches and high-concentration capsaicin patches, anticonvulsants such as gabapentin, and antidepressants such as duloxetine or amitriptyline. Your physician will recommend options based on your symptom pattern, other health conditions, and medication history.
