Why Do I Feel Needle Pricks In My Skin? A Comprehensive Guide To Paresthesia

Have you ever felt like pins and needles were pricking your skin, even though nothing was there? This tingling, prickling, numb sensation is called paresthesia, and it has a variety of potential causes.

If you’re short on time, here’s a quick answer: Paresthesia, or the feeling of ‘pins and needles’ in the skin, is usually caused by nerve issues or pressure on nerves. Common causes include carpal tunnel syndrome, vitamin B deficiency, diabetes complications, and more.

In this comprehensive 3000 word guide, we will explore all the possible causes of paresthesia, when you should see a doctor, and how to find relief from the uncomfortable ‘needle prick’ sensations.

What Is Paresthesia?

Paresthesia is a neurological condition that causes abnormal sensations in the skin, such as tingling, numbness, or a feeling of needle pricks. These sensations can occur spontaneously or be triggered by certain actions, such as applying pressure to a specific area or moving a limb.

Definition and Description of Symptoms

Paresthesia is characterized by abnormal sensations in the skin that are not caused by external factors. The most common symptoms include tingling, numbness, burning, and a feeling of “pins and needles.”

These sensations can occur in any part of the body, but they are most commonly felt in the hands, feet, arms, and legs.

Individuals experiencing paresthesia may also have difficulty with coordination and balance, as well as muscle weakness. The severity and duration of symptoms can vary greatly from person to person, with some individuals experiencing occasional episodes and others experiencing persistent symptoms.

Types of Paresthesia

There are several different types of paresthesia, each with its own underlying causes and characteristics.

  • Transient paresthesia: This type of paresthesia is temporary and often occurs due to pressure on nerves or blood vessels, such as when sitting or sleeping in an awkward position. The symptoms usually resolve on their own once the pressure is relieved.
  • Chronic paresthesia: Chronic paresthesia refers to persistent or recurring symptoms that last for extended periods of time. This can be caused by underlying medical conditions, such as nerve damage, diabetes, multiple sclerosis, or vitamin deficiencies.
  • Idiopathic paresthesia: Idiopathic paresthesia refers to cases where no underlying cause can be identified. This can be frustrating for individuals experiencing the symptoms, as it is difficult to determine the exact cause and find appropriate treatment.

If you are experiencing paresthesia, it is important to consult with a medical professional to determine the underlying cause and develop an appropriate treatment plan. They may conduct a physical examination, order diagnostic tests, or refer you to a specialist for further evaluation.

What Causes Paresthesia?

Paresthesia, commonly known as the sensation of needle pricks or tingling in the skin, can be caused by various factors. Understanding the underlying causes is crucial in managing and treating this condition effectively.

Nerve Damage or Disorders

One of the primary causes of paresthesia is nerve damage or disorders. Conditions such as carpal tunnel syndrome, herniated discs, and peripheral neuropathy can lead to abnormal sensations in the skin. These conditions can be caused by injuries, repetitive movements, or underlying medical conditions.

Vitamin Deficiencies

Vitamin deficiencies, particularly deficiencies in vitamin B12, can also contribute to the development of paresthesia. Vitamin B12 plays a crucial role in maintaining the health of nerve cells. A lack of this vitamin can lead to nerve damage and result in abnormal sensations in the skin.

It is important to maintain a balanced diet and ensure an adequate intake of essential vitamins to prevent deficiencies.

Autoimmune Disorders

Autoimmune disorders, such as multiple sclerosis and lupus, can cause paresthesia as well. These conditions occur when the immune system mistakenly attacks healthy cells, including nerve cells. The damage to the nerves can result in abnormal sensations in the skin.

Proper management of autoimmune disorders through medication and lifestyle changes can help alleviate symptoms of paresthesia.

Diabetes Complications

Individuals with diabetes may experience paresthesia as a complication of their condition. High blood sugar levels can damage nerves over time, leading to paresthesia. It is essential for individuals with diabetes to maintain good blood sugar control to prevent or manage this symptom.

Regular monitoring of blood sugar levels and following a healthy lifestyle are crucial in preventing diabetes-related complications.


Paresthesia can also occur during pregnancy due to hormonal changes and increased pressure on nerves. The growing uterus can compress nerves, leading to abnormal sensations in the skin. In most cases, paresthesia during pregnancy is temporary and resolves after childbirth.

However, it is advisable to consult with a healthcare professional to ensure a healthy pregnancy and manage any symptoms.


Some medications, including certain chemotherapy drugs and anticonvulsants, can cause paresthesia as a side effect. These medications can affect nerve function and lead to abnormal sensations in the skin.

It is important to discuss any concerns or side effects with a healthcare provider, who may be able to adjust the dosage or prescribe alternative medications.

It is important to note that paresthesia can have various causes, and it is essential to consult with a healthcare professional for an accurate diagnosis and appropriate treatment. Proper management of underlying conditions, maintaining a healthy lifestyle, and following medical advice can help alleviate symptoms and improve overall well-being.

When to See a Doctor

Experiencing needle pricks in your skin can be a concerning and uncomfortable sensation. While it is often harmless and temporary, there are certain situations where it is important to seek medical attention.

A doctor can assess your condition, perform necessary tests, and determine the appropriate course of action to alleviate your symptoms.

After Injury or Trauma

If you start experiencing needle pricks in your skin following an injury or trauma, it is advisable to consult a healthcare professional. In some cases, trauma can cause nerve damage or irritation, leading to paresthesia.

Seeking medical attention can help identify any underlying issues and ensure proper treatment to aid in your recovery.

Remember, it is always better to err on the side of caution when it comes to your health. If you have any concerns or questions about the needle prick sensation in your skin, don’t hesitate to reach out to a medical professional for guidance.

They are equipped with the knowledge and expertise to provide you with the necessary care and support.

Diagnosing Paresthesia

When experiencing needle pricks or tingling sensations in your skin, it is important to seek medical attention to determine the underlying cause. Diagnosing paresthesia involves a comprehensive evaluation of your medical history, physical examination, and several diagnostic tests.

Medical History and Physical Exam

During the medical history assessment, your healthcare provider will ask you detailed questions about your symptoms, their duration, and any associated factors. They will also inquire about your medical history, including any underlying conditions or recent injuries that could be contributing to your symptoms.

Additionally, a physical examination will be conducted to assess your neurological function and identify any abnormalities.

Blood Tests

Blood tests are commonly performed to help diagnose paresthesia. These tests can detect underlying medical conditions such as diabetes, vitamin deficiencies, thyroid dysfunction, or autoimmune disorders that may be causing your symptoms.

By analyzing your blood samples, healthcare professionals can gather valuable information that will aid in the diagnostic process.

Nerve Conduction Studies

Nerve conduction studies are a specialized diagnostic test used to evaluate the functioning of your nerves. During this procedure, small electrodes are placed on your skin, and a mild electrical impulse is applied to stimulate the nerves.

The response of your nerves is then measured, allowing healthcare professionals to assess the speed and strength of nerve signals. This test can help identify nerve damage or compression that may be causing paresthesia.

Imaging Tests

In some cases, imaging tests such as X-rays, magnetic resonance imaging (MRI), or computed tomography (CT) scans may be necessary to further evaluate the underlying cause of paresthesia. These tests can provide detailed images of your bones, muscles, and nerves, helping to identify any structural abnormalities or injuries that may be contributing to your symptoms.

It is important to note that the specific diagnostic tests used may vary depending on your individual case and the suspected cause of your paresthesia. Your healthcare provider will determine the most appropriate tests based on your symptoms, medical history, and physical examination findings.
