Paresthesia refers to abnormal sensations in the body, often described as a tingling, numbness, burning, prickling, or “pins and needles” sensation. It is a result of abnormal nerve function and can occur in various parts of the body, including the limbs, hands, feet, and sometimes the face. Paresthesia can be caused by several factors, including:
- Pressure on Nerves: When nerves are compressed or pinched, such as in conditions like carpal tunnel syndrome or a herniated disc, it can lead to paresthesia in the affected area.
- Nerve Damage: Injuries, trauma, or certain medical conditions like peripheral neuropathy, multiple sclerosis, or diabetes can damage the nerves, causing paresthesia.
- Poor Blood Circulation: Reduced blood flow to a specific area can result in paresthesia. Certain conditions and blood vessel disorders can contribute to this symptom.
- Nutritional Deficiencies: Lack of certain vitamins and minerals, particularly vitamin B12, can lead to nerve damage and paresthesia.
- Infections or Inflammation: Conditions like shingles, Lyme disease, or autoimmune disorders can cause inflammation or irritation of the nerves, resulting in paresthesia.
Paresthesia can be temporary or chronic, depending on the underlying cause. It may come and go or persist for extended periods. If you experience persistent or recurrent paresthesia without an apparent cause, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
