Brief Summary: Idiopathic Small Fiber Neuropathy called SFN for short is a condition where nerves that sense pain have become damaged and often painful SFN pain is common and it can affect sleep memory health and overall quality of life

Pregabalin is a drug commonly used to treat painful conditions like nerve pain It has been available to doctors for many years and many studies have been performed to evaluate its effectiveness In these studies pregabalin has been shown to be very effective in the treatment of nerve pain with fewer side effects than many other medications currently available The purpose of the study is to determine if pregabalin relieves pain more effectively than a pill containing no medication called a placebo The study will also investigate any side effects as well as the effectiveness and safety of the medication
Detailed Description: Painful small fiber sensory neuropathy SFN is relatively common and a disabling medical condition It is the most common type of painful sensory neuropathy in patients older than 50 years of age It is defined as a neuropathy that exclusively or predominantly affects the A-δ small myelinated and nociceptive C unmyelinated nerve fibers and their functions The neuropathic pain associated with SFN is described by the patients as burning feet are on fire sharp knife-like jabbing or pins and needles shooting and aching pain in the toes and feet The feet are described as tingling numb or feeling tight wooden or dead The pain is disabling and often exacerbated at night interfering and disrupting the sleep pattern Allodynia and cramps may also occur Some patients also describe pressure induced pain in their feet with standing and walking The autonomic nerves may be involved leading to increased or decreased sweating facial flushing skin discoloration and erectile dysfunction in up to 40 of males On examination there is a dramatic mismatch between the symptoms and observable deficits in SFN Only abnormal findings are the loss of pinprick and temperature sensations in feet that may extend up to the knees Touch sensation may be diminished but other sensations are usually preserved By definition patients with SFN are allowed to have minor involvement of large fibers distally with reduced vibration in toes but the ankle reflexes are usually preserved

This study will be of a crossover design thus minimizing the number of subjects needed Each patient will act as hisher own control Previous studies of pregabalin have shown that the desired effect is achieved by eight weeks of treatment Therefore each patient will start on either placebo or pregabalin They will be assessed on this treatment arm for eight weeks There will be a two-week drug tapering and washout period before switching treatments followed by re-assessment for an additional eight weeks This design minimizes the amount of time that the patient will be treated with placebo
