Mravenení

Mravenčení, also known as paresthesia, is a subjective sensation of tingling, prickling, or numbness that can occur in various parts of the body. It is often described as the feeling of "pins and needles." This sensation is typically temporary and harmless, resolving on its own once the underlying cause is addressed.

Common causes of mravenčení include prolonged pressure on a nerve, such as sitting or sleeping in an awkward position. This pressure can temporarily reduce blood flow and nerve signal transmission, leading to the characteristic tingling. Other frequent causes include nerve compression due to injury, repetitive motions, or conditions like carpal tunnel syndrome.

In some instances, mravenčení can be a symptom of more serious underlying medical conditions. These can include neurological disorders like multiple sclerosis or peripheral neuropathy, which can affect the nerves throughout the body. Metabolic conditions such as diabetes, vitamin deficiencies (particularly B vitamins), or thyroid problems can also manifest with paresthesia. Furthermore, certain medications or exposure to toxins can trigger this sensation.

If mravenčení is persistent, severe, accompanied by weakness, pain, or other concerning symptoms, it is advisable to consult a healthcare professional to determine the specific cause and receive appropriate treatment. Diagnosis often involves a physical examination, medical history review, and potentially nerve conduction studies or imaging tests.
