Small Fiber Neuropathy Symptoms Diagnosis and Treatment
Small fiber neuropathy is really an interestingcondition because it consists typically of just burning, numbness, pain of the feet,sometimes the hands later on without necessarily having any abnormalities on your EMG or nerveconduction study. So what I tell patients and actually residents or students who trainunder us is that a normal nerve conduction study does not exclude a neuropathy. And wewill confirm this by doing additional testing, specifically the nervous the the examinationat the bedside asking patients about their symptoms, for example, loss of sensation tocool or or hot temperatures, loss of pain sensation and also doing skin biopsies wherewe look at nerve densitiesthe skin both
from the calf and the thigh as well as doinga special test that looks at sweat function bothyour footin the legs as well asthe feet to gauge the level of small fiber nerve damage. Small fiber neuropathy typicallywill progress unless the underlying cause is identified and reversed. Diabetes of coursebeing the most common cause is always screened for. But once the more common causes are excludedand the focus becomes on excluding any underlying secondary disease process but also controllingpain because if patients' symptoms of pain are generally controlled they tend to do prettywell and really have no other major functional deficits. I've really become interested overthe years is how interconnected neurology
and rheumatology are and one thing I oftendo on patients who have unexplained small fiber even autonomic neuropathy is have themsee rheumatology or get evaluated for connective tissue disorders like lupus or Sjogren's orsarcoid and sometimes even if we are not directly involvedtreating the patients, this canbe the first sign of an underlying connective tissue disorder that can then be brought tothe attention of rheumatology and adessed from their standpoint.
Fibromyalgia Fibromyalgia patients pain might stem from smallfiber polyneuropathy
Fibromyalgia. think it's allyour head.it may beyour skin too Fibromyalgia patients' pain might stem fromsmallfiber polyneuropathy A reportHelio showed that almost halfof patients diagnosed with fibromyalgia tested positive for smallfiber polyneuropathy, aperipheral nerve disease that might cause their chronic widespread pain, according torecent study results. quot;Until now, there has been no good idea aboutwhat causes fibromyalgia, but now we have evidence for some but not all patients,quot; researcherAnne Louise Oaklander, MD, PhD, director of the Nerve Injury Unit at Massachusetts General's neurology department, saida
press release. quot;This provides some of thefirst objective evidence of a mechanism behind some cases of fibromyalgia, and identifyingan underlying cause is the first step toward finding better treatments.quot;Comment: A disease that is poorly understood is finally getting some attention.
