puutuneisuus

Puutuneisuus is a Finnish term that translates to numbness in English. It describes a diminished ability to feel touch or temperature, and is often accompanied by tingling, burning, or a "pins and needles" sensation. Puutuneisuus is a symptom, not a disease, and can affect any part of the body, most commonly the hands, feet, arms, or legs. It may be temporary or persistent and can arise suddenly or develop gradually.

Causes of puutuneisuus are varied and include nerve compression or injury (for example, carpal tunnel syndrome or sciatica), peripheral neuropathy (such as diabetic neuropathy), vitamin deficiencies (notably vitamin B12), alcohol use, infections, autoimmune conditions, and side effects of medications. Circulatory problems, frostbite, and stroke can also produce numbness. In some cases, puutuneisuus reflects one-time pressure on a nerve, while in others it signals chronic conditions that require ongoing management.

Diagnosis typically begins with a clinical history and neurological examination. Additional tests may include blood tests (glucose control, vitamin levels, thyroid function), imaging studies, and nerve conduction studies or electromyography to assess nerve function. The goal is to identify the underlying cause and guide treatment.

Treatment focuses on addressing the root cause when possible. This may involve treating diabetes, correcting deficiencies, adjusting medications, relieving nerve compression, or using physical therapy and occupational therapy. Pain relief and coping strategies may be used for chronic numbness. Prognosis varies widely and depends on the cause and timeliness of treatment.
