That depends almost entirely on the cause, which is why identifying it matters more than naming the neuropathy. Where the cause is found and controlled, many neuropathies stabilise. Where it is not, or where none is identified, slow progression over years is the usual pattern.

Peripheral neuropathy is a description, not a diagnosis, and the conditions behind it behave very differently. A neuropathy from vitamin B12 deficiency can stop advancing once the deficiency is corrected. One from alcohol improves in some people who stop drinking. One from diabetes tends to advance while glucose stays high. An inflammatory neuropathy may respond to immune treatment. A hereditary neuropathy progresses on its own timetable. Grouping these together and asking whether neuropathy worsens produces an answer that fits none of them.
The commonest pattern is length-dependent, meaning the longest nerves fail first, so numbness and burning begin in the toes and move upwards over years before the fingers are involved. Sensory symptoms usually come well before weakness. As it advances, loss of position sense contributes to unsteadiness in the dark or on uneven ground, which is a falls risk that people rarely connect to their feet. Rapid progression over weeks, marked asymmetry, or prominent weakness early all argue for a different and more urgent process.
EMG and nerve conduction studies establish whether the problem is axonal or demyelinating, which narrows the differential sharply, and they grade severity so a later study can be compared against a real baseline rather than a recollection. They also identify the mimics that get treated as neuropathy for months: lumbar radiculopathy, nerve entrapment at the wrist or elbow, and myelopathy. Both offices run their own AANEM-accredited electrodiagnostic laboratory, so the study and its interpretation happen in the same place.
Where a cause is identified, treating it is the only route to changing the trajectory: glucose control, B12 replacement, stopping alcohol, treating an inflammatory cause, reviewing a culprit medication. Where the search is thorough and no cause emerges, which happens in a substantial minority, the honest position is that the neuropathy is likely to advance slowly and that treatment addresses pain, function and falls risk instead. Repeat testing is done when the picture changes rather than on a schedule.
Clinical Neurology Specialists has been physician-owned since 1998, when Leo Germin, M.D., FAANEM founded it. Five board-certified neurologists and four advanced practice providers see patients at the Las Vegas and Henderson offices, each with its own AANEM-accredited electrodiagnostic laboratory.
Clinical Neurology Specialists is an adult outpatient neurology practice for patients 18 and older. The practice performs no surgery and operates no imaging suite, infusion suite or interventional pain programme, and provides no emergency or inpatient care.
