Polyneuropathie: Ursachen, Nervenschmerz und Frequenztherapie

From Herbert Eder – an internationally sought-after frequency expert

Edited on October 30, 2026

Polyneuropathie kann Schmerzen, Gefühlsverlust, Schwäche und Störungen unwillkürlicher Körperfunktionen verursachen. Ursachenbehandlung, Symptomlinderung und Schutz vor Folgeschäden sind deshalb getrennte Aufgaben. Weniger Brennen bedeutet beispielsweise nicht automatisch, dass eine Fußverletzung wieder sicher gespürt wird. [1][7][9]

As Herbert Eder ordne ich Frequency therapy an diesen unterschiedlichen Zielen ein. Ein Verfahren zur Schmerzbeeinflussung muss seine Aussage auf diesen Endpunkt begrenzen, solange eine Nervenregeneration nicht belegt ist.

What the Pattern of Complaints Reveals

Symptoms often first appear in the feet or hands. Some people experience a burning sensation and stabbing pain, while others report numbness or unsteadiness when walking. The specific symptoms depend on which nerves are affected. Symptoms may be persistent or fluctuate. Have any new sensory disturbances, loss of strength, or a foot wound that isn’t healing properly examined as soon as possible. ^[1]

During your appointment, describe as specifically as possible what has changed: Do both feet feel the same? Is touch uncomfortable or barely noticeable? Do you stumble more often, or is it harder to lift your foot? How long has this change been going on? A description like this is more helpful than trying to come up with a diagnosis on your own before the appointment.

The cause warrants a separate investigation

Possible causes include diabetes, alcohol abuse, certain medications, vitamin B12 deficiency, excessive vitamin B6 intake, and kidney, immune, or infectious diseases. Hereditary forms are also possible. In some cases, despite diagnostic evaluation, the cause of nerve damage remains unknown. The umbrella term “polyneuropathy” therefore does not specify either the underlying cause or a single appropriate treatment. ^[2]

An existing medical condition does not necessarily explain every case of nerve damage. The neurological guideline warns against jumping to conclusions about possible causes. The key factor is whether the patient’s medical history, the distribution of symptoms, and the test results are consistent. Multiple contributing factors can also complicate the assessment. In cases with an unusual course, a re-evaluation by a specialist is advisable. ^[3]

Bring a complete list of your medications and dietary supplements. This includes over-the-counter products and previous cancer treatments. Information about alcohol use and potential workplace stressors is medical information, not a moral judgment. Have your prescribed medications reviewed instead of stopping them on your own.

How to Diagnose Polyneuropathy

Am Anfang stehen die Krankengeschichte und eine Untersuchung von Gefühl, Kraft und Reflexen. Blutuntersuchungen können beispielsweise auf Diabetes oder einen Vitamin-B12-Mangel hinweisen. In der neurologischen Practice kommen je nach Fragestellung Messungen der Nervenleitung und der elektrischen Muskelaktivität hinzu. Mit ihnen lässt sich genauer beurteilen, welche Nervenfunktionen beeinträchtigt sind. Eine Nervenbiopsie ist nur in ausgewählten Situationen erforderlich. ^[4]

In small-fiber neuropathy, small nerve fibers are primarily affected. Standard nerve conduction studies may then show normal results. Among other things, the guideline describes targeted assessments of temperature and pain sensation, as well as a skin biopsy if necessary. A normal result from a single measurement therefore does not rule out every form of nerve damage; conversely, a burning sensation alone does not prove the presence of small-fiber neuropathy. ^[3]

After every major test, ask what question it was intended to answer and how the results will affect your treatment plan. If the cause remains unclear, schedule a follow-up appointment to monitor your progress. This ensures a clear and transparent diagnostic process without automatically requiring every possible specialized test.

What Changes Are Urgent

Sudden or rapidly worsening sensory disturbances and paralysis require urgent evaluation. You should seek immediate help, especially if these symptoms are accompanied by altered consciousness, severe headaches, or other serious symptoms. The Austrian health portal classifies such developments as an emergency: call 144 for an ambulance, or 112 for the Europe-wide emergency number. A previously diagnosed case of polyneuropathy is no reason to wait and see if new acute symptoms develop. ^[5]

Rapidly progressing weakness that begins with tingling and spreads to other parts of the body may, for example, be consistent with Guillain-Barré syndrome. This condition can also affect breathing, swallowing, and circulation. It is a condition that requires prompt treatment in a hospital. Breathing or swallowing problems accompanied by new weakness require immediate medical attention; based on this description alone, it is not possible to make a reliable diagnosis at home. ^[6]

Address the root causes and set realistic goals

Treatment depends on the underlying cause: In cases of diabetes, metabolic control is assessed; if a vitamin B12 deficiency is confirmed, it is treated. If a medication is involved, a doctor will determine whether the treatment can be adjusted. Certain immune-mediated forms require specialized therapies. These are not suitable for every type of polyneuropathy. The extent to which nerves recover depends on the cause and the extent of the damage; not every change can be completely reversed. ^[7]

Ask for an explanation of whether the primary goal is recovery, preventing further damage, or better managing persistent symptoms. This helps avoid unrealistic expectations and makes progress easier to recognize. If alcohol is a factor, a safe, medically supervised approach to managing it should be included in the plan; in cases of addiction, a guided transition away from alcohol should be planned.

Muscle weakness and limited mobility can also be treated with physical therapy. Depending on your needs, orthotics or walking aids may be helpful. Conditions such as bladder dysfunction or digestive problems also require targeted treatment. You should be sure to mention these issues during your consultation, even if the appointment was initially scheduled because of foot pain. ^[7]

Nerve pain requires the right treatment

For neuropathic pain, options include amitriptyline, duloxetine, gabapentin, and pregabalin, among others. The most appropriate option depends on comorbidities, other medications, and potential side effects. The NICE guideline recommends an early follow-up after starting or changing a medication, as well as further follow-ups. If a medication is not sufficiently effective or is poorly tolerated, switching to another option may be advisable. Such changes are planned in consultation with the treating physician’s office. ^[8]

A medication from the class of antidepressants can be used to treat pain, even if you do not have depression. The name of the medication does not, therefore, explain the reason for your prescription. Ask about the goal of the treatment, the most common side effects, and when you plan to evaluate the benefits together. ^[7]

In cases of diabetic neuropathy, the NIDDK explicitly points out that pain-relieving medications do not reverse the nerve damage itself. Therefore, less burning sensation does not automatically mean that you can reliably perceive pressure or injury again. This distinction remains important even if your sleep and your ability to cope improve as a result of pain treatment. ^[9]

Don’t just rate a number on the pain scale. Also note whether you’re sleeping better, can sit for longer periods, or feel more confident moving around. Fatigue and dizziness can limit the benefits you experience. Meaningful treatment success should be evident in your daily life; bothersome side effects should be included in your feedback just as much as the intensity of your pain. ^[8]

Check vitamins carefully

„Good for the nerves“ is not a sufficient reason for high vitamin doses. The Australian Therapeutic Goods Administration (TGA) warns of neuropathies caused by vitamin B6 in dietary supplements. B6 may also be present in magnesium, zinc, or multivitamin products. When taking multiple supplements, the amounts add up. Based on the reports, it is not possible to determine a reliably safe minimum dose or duration of use for individual risk assessment. This refers specifically to dietary supplements, not to a typical intake of B6 from food. ^[10]

Take photos of the front label, the list of ingredients, and the daily dose for all products. This will help us understand during our conversation exactly what you are actually taking. If new symptoms occur around the same time you start taking a supplement, please report this promptly. A diagnosed deficiency and preventive use without a proven need are two different situations.

Protect Your Feet and Stay Safe on the Move

If you have diabetes and reduced sensation, you should inspect your feet daily, including the soles and the spaces between your toes. A mirror or someone to assist you can help. Look for pressure points, blisters, redness, and sores. Before putting on your shoes, check them for foreign objects and make sure to wear well-fitting shoes. Protect your feet from hot water. Do not cut away calluses yourself, and do not use irritating corn remedies if you have nerve damage. ^[11]

A new wound, increasing redness, warmth, or swelling should be evaluated by a doctor promptly. The absence of pain is not a sign that everything is fine if you have reduced sensation. This is especially true for people with diabetes, when a minor injury may go unnoticed. Let us show you which foot care tasks you can handle on your own and when professional assistance is needed. ^[11]

When it comes to staying active in everyday life, a manageable plan is more helpful than a demanding program that you avoid out of uncertainty. Discuss safe exercises and any assistive devices you might need. Also check for practical obstacles: a dark path to the bathroom, loose rugs, or shoes that don’t provide good support. An assistive device can enable freedom of movement rather than restrict it.

Classifying TENS, Frequency Lists, and Detoxification Programs

TENS transmits weak electrical impulses through electrodes placed on the skin and is used for pain management. The NINDS describes it as a potential adjunct for treating nerve pain. Whether this treatment is suitable for you should be evaluated by a medical professional. Any potential pain relief does not imply nerve regeneration or the effectiveness of any specific frequency lists. ^[2]

If toxic exposure is suspected, a targeted medical evaluation is necessary. The FDA warns against over-the-counter chelation products marketed for alleged detoxification: Such products can cause serious side effects. Medically indicated treatment for specific types of metal poisoning is distinct from a generic „detox“ program. A sales pitch or an unreliable test associated with it does not in itself constitute evidence of poisoning requiring treatment. ^[12]

Have three questions ready for your next checkup: What do we know so far about the cause? What steps can improve my daily life? And how can we prevent further damage? A plan that answers these questions and is adjusted as circumstances change offers more guidance than a general promise to restore nerve function with a single procedure.

Polyneuropathie und Frequenztherapie: Schmerzreduktion ist keine nachgewiesene Regeneration

TENS wird in der NINDS-Information als mögliche Ergänzung gegen Nervenschmerzen beschrieben. Ein solcher Ansatz liefert keinen allgemeinen Nachweis für Frequenzlisten oder die Wiederherstellung geschädigter Nerven. Entscheidend bleiben das konkrete Verfahren und eine fachlich geprüfte Eignung. [2]

Auch während eines angenehmen Anwendungseffekts bleiben Ursachenklärung und Fußschutz notwendig. Unbemerkte Wunden können bei reduziertem Gefühl relevant sein. Zusätzliche hoch dosierte Vitamine sind keine pauschale Nervenpflege: Vitamin B6 aus mehreren Präparaten kann selbst zu einer Neuropathie beitragen. [10][11]
