Understanding Head Numbness : Causes, Symptoms, and Treatment

Conditions such as diabetes, multiple sclerosis, and even common ailments like the cold can potentially lead to sensations of numbness in the head. While in many cases, this symptom is benign and not a cause for immediate concern, if it starts to impede your regular activities, seeking medical advice is advisable.⁽¹⁾

Numbness, medically known as paresthesia, is a sensation commonly experienced in the arms, legs, hands, and feet. However, feeling numbness in the head is comparatively less frequent. It’s important to note that, in most instances, experiencing paresthesia in the head is not a cause for immediate worry.⁽²⁾

In the context of diabetes, elevated blood sugar levels can affect nerve function, potentially leading to tingling or numbness, not only in the extremities but occasionally in the head as well. In cases of multiple sclerosis, a condition characterized by damage to the protective covering of nerve fibers, sensations of numbness can occur anywhere in the body, including the head.⁽³⁾

Even something as commonplace as the common cold can lead to temporary sensations of numbness in the head, often due to congestion and inflammation affecting nerves in the face and scalp.

Most often, these conditions impact the nerves responsible for sensation in the scalp and head. Several crucial nerve clusters link your brain to different regions of your face and head. When these nerves face inflammation, compression, or damage, it can lead to sensations of numbness. Additionally, restricted blood supply can also result in this sensation.

Some of the other potential causes of head numbness may include:⁽⁴⁾

1. Autoimmune Disorders: Conditions like diabetes can lead to permanent nerve damage, known as diabetic neuropathy. Multiple sclerosis is also associated with numbness.
2. Sinus Conditions: Conditions like allergic rhinitis, common colds, and sinusitis can lead to head numbness due to congestion and inflammation affecting nerve function.
3. Medications and Substances: Certain drugs like anticonvulsants, chemotherapy medications, as well as illicit drugs and alcohol, can induce sensations of numbness.
4. Headaches: Various types of headaches including cluster headaches, eyestrain headaches, migraines, and tension headaches can be linked to head numbness.
5. Infections: Infectious conditions like encephalitis, Lyme disease, shingles, and tooth infections can lead to nerve inflammation and subsequent numbness.
6. Injuries: Direct head or brain injuries such as concussions and head trauma can cause numbness if they lead to nerve damage.
7. Other Conditions: Conditions ranging from brain tumors, high blood pressure, poor posture, seizures, to strokes can also contribute to head numbness.

Recognizing the underlying cause of head numbness is crucial for appropriate management and treatment. If head numbness becomes persistent or severe, or if it is accompanied by other concerning symptoms like difficulty speaking, weakness, or loss of coordination, it is important to seek prompt medical attention. This could potentially indicate a more serious underlying issue that requires proper evaluation and treatment. Always consult a healthcare professional for personalized advice and diagnosis.

Signs of numbness in the head can vary in their presentation and may include the following:⁽⁵⁾

• Tingling Sensation: Individuals may experience a tingling or “pins and needles” sensation in their scalp or head.
• Loss of Sensation: Numbness often involves a partial or complete loss of sensation in the affected area. This can result in difficulty feeling touch or temperature changes.
• Reduced Ability to Move: In some cases, head numbness may be accompanied by weakness or a reduced ability to move certain parts of the face or head.
• Altered Sensation Quality: Individuals might perceive unusual sensations in the head, such as a feeling of heaviness or tightness.
• Unilateral or Bilateral: Head numbness can occur on one side (unilateral) or affect both sides (bilateral) of the head, depending on the underlying cause.
• Accompanying Symptoms: Depending on the cause, head numbness may be associated with other symptoms, such as headache, dizziness, vision changes, nausea, or difficulty speaking.

However, if you encounter head numbness in conjunction with any of the following, it is crucial to seek immediate medical attention:⁽⁶⁾

• A recent head injury
• Numbness extending to other parts of your body
• Complete numbness in an entire arm or leg
• Weakness in your face or in other parts of your body
• Confusion or difficulties with speech
• Vision abnormalities
• A sudden, unusually severe headache
• Loss of bladder or bowel control

It is important to note that while head numbness can result from various causes, including benign ones like temporary pressure on nerves or minor injuries, it can also be a sign of more serious medical conditions. For example, unilateral facial numbness could potentially indicate a stroke and should be promptly evaluated by a medical professional.

If you experience persistent or severe head numbness, especially if it is accompanied by other concerning symptoms, it is advisable to seek medical attention for a thorough evaluation and diagnosis.

Experiencing head numbness upon waking may indicate that your sleeping position is impeding blood flow to a nerve. Consider sleeping on your back or on your side, ensuring your head, neck, and spine are in a neutral alignment.

Unilateral head numbness, where only one side of the head is affected, can manifest in different ways. It may encompass the entire right or left side, or be limited to specific areas like the temple or the back of the head. Unilateral numbness, particularly sudden onset, should be evaluated immediately

This condition can be associated with various underlying causes, including:

• Bell’s palsy⁽⁷⁾
• Infections
• Migraines
• Multiple sclerosis⁽⁸⁾

On the other hand, people experiencing anxiety may also occasionally describe sensations of numbness or tingling in their head. In certain cases, a surge of panic can induce these sensations, affecting the scalp, face, and possibly other regions of the body.

Although the precise connection between anxiety and head numbness remains somewhat unclear, it is likely associated with the body’s instinctual fight-or-flight response. During moments of perceived threat, blood flow is redirected to support functions crucial for confronting or evading the threat. Consequently, areas of the body not prioritized in this response may experience transient sensations of numbness or tingling. While anxiety can cause these sensations, it’s essential to rule out other medical causes before attributing numbness to anxiety alone.

When you go to your doctor complaining of numbness in your head, your doctor will perform a thorough physical examination and inquire about all your symptoms and medical background. They may inquire about the onset of the numbness and whether any other symptoms emerged concurrently.

Furthermore, your doctor may recommend a combination of the following tests to pinpoint the underlying cause of your head numbness:

• Blood tests
• Neurological assessments
• Nerve conduction studies and electromyography
• MRI (Magnetic Resonance Imaging)
• CT scan (Computed Tomography)
• Nerve biopsy

Due to the diverse range of conditions that can lead to head numbness, it may require some time to precisely determine the root cause of your symptoms.

The approach to treating head numbness hinges on accurately identifying and addressing the underlying cause. Once a diagnosis is established, tailored treatments are typically employed. For instance, in cases where diabetes is the culprit, the focus is on achieving stable blood sugar levels. This is often accomplished through a combination of dietary adjustments, regular exercise, and, if necessary, insulin therapy.

In scenarios where head numbness arises from more common causes like colds or mild to moderate headaches, over-the-counter medications can be effective in providing relief.

When posture plays a role in head numbness, making adjustments to one’s position, employing ergonomic aids, and incorporating regular movement can be beneficial. Specific exercises, including those focused on deep breathing, can also be instrumental in improving posture and alleviating associated symptoms.

Exploring alternative treatments like acupuncture and massage may offer additional avenues for relief. These approaches have been known to enhance blood circulation, potentially mitigating head numbness.

It is crucial to maintain open communication with your healthcare provider, especially if head numbness arises after starting a new medication. This information can be pivotal in assessing the potential side effects or interactions of the prescribed treatment.

Remember, individual responses to treatments may vary, so it’s important to consult with your healthcare provider to determine the most appropriate course of action for your specific situation.

Head numbness can arise from various causes, ranging from common issues like tension headaches to potentially concerning conditions such as diabetes or neurological disorders. Prompt medical attention is essential for accurate diagnosis and tailored treatment. This may include lifestyle adjustments, medication, or alternative therapies like acupuncture. Early intervention and open communication with a healthcare provider are crucial for managing and alleviating head numbness, promoting overall well-being and comfort.
