Numbness in the head can be caused by a variety of factors, including nerve damage, nerve inflammation, or underlying health conditions. Swelling in the head muscle can be indicative of occipital neuralgia, a headache disorder causing nerve inflammation and irritation, resulting in pain and potential numbness. This condition can be treated with medication, steroid injections, or surgery, although the latter may lead to permanent scalp numbness. Other potential causes of head numbness include migraines, allergies, anxiety, and stress, as well as more serious conditions like strokes or multiple sclerosis (MS). Determining the underlying cause of head numbness is crucial for appropriate treatment.

What You'll Learn
Numbness can be caused by nerve damage or nerve irritation
Numbness in the head can be caused by nerve damage or nerve irritation. Numbness is a loss of feeling or sensation in a body part. It can be complete (no feeling at all) or partial (less feeling than usual). While it usually affects the hands, fingers, feet, arms, or legs, it can occur in any part of the body, including the head.
There are two greater occipital nerves, one on each side of the head, that emerge from the upper neck and run through muscles at the back of the head into the scalp. Irritation or inflammation of these nerves can cause a sharp, zapping, electric, or tingling pain, along with numbness in the affected area. This condition is known as occipital neuralgia, which can be treated with medications, steroid injections, botulinum toxin injections, or surgery.
Nerve damage can occur due to various factors, including alcohol or tobacco use, chemotherapy drugs, radiation therapy, injuries, and vitamin deficiencies. Certain medical conditions can also lead to nerve damage and numbness, such as diabetes, kidney disorders, multiple sclerosis, and hypothyroidism. In some cases, sleeping in a position that restricts blood flow to a nerve can also cause temporary numbness.
Nerve irritation or damage can disrupt the normal functioning of nerves, impairing their ability to transmit sensory signals effectively. This disruption can result in a loss of sensation, difficulty in feeling touch or temperature, and impaired balance and coordination. It is important to consult a healthcare professional to determine the underlying cause of numbness and receive appropriate treatment.

Head injuries can cause numbness
Direct blows to the head can cause damage to nerve endings, leading to numbness in the affected area. This can be caused by concussions, skull fractures, or hematomas, which put pressure on the nerve endings. Nerve damage can also occur throughout the body, including the neck and spinal cord, resulting in numbness in associated areas.
Injuries to the head can also cause swelling and inflammation, which can lead to numbness by putting pressure on nerve endings. In addition, concussions can disrupt the normal functioning of the brain and the nervous system, resulting in numbness and other symptoms. It is important to note that numbness or tingling in the head after a concussion can be a sign of a serious underlying condition.
If you are experiencing numbness after a head injury, it is important to seek medical attention as soon as possible. Doctors will conduct a physical examination and ask about your symptoms and medical history to determine the underlying cause of your numbness. Treatment options may include sensory reeducation, acupuncture, and electrical stimulation, depending on the cause and severity of the numbness.
Head injuries can range from minor to severe, and numbness is a common symptom that can occur after such an injury. Numbness can affect different parts of the body, including the head, and it is important to identify and address the underlying cause through proper diagnosis and treatment.

Underlying health conditions can cause numbness
Numbness in the head can be caused by several underlying health conditions. Numbness is often associated with other sensations, such as difficulty feeling touch or temperature on the scalp or face. It is usually a sign of a problem with the nerves, although it can also be a common symptom of many different medical conditions.
Head injuries, such as concussions or trauma, can cause numbness if they damage nerves. Posterior Reversible Encephalopathy Syndrome (PRES) is a neurological disorder characterized by swelling and inflammation in the brain that can also lead to numbness. In addition, sleeping in a position that restricts blood flow to a nerve can cause temporary numbness, which can be alleviated by changing sleep positions.
Certain medical conditions can also lead to head numbness. For example, diabetes can cause numbness, and treatment in such cases focuses on stabilising blood sugar levels through diet, exercise, and insulin treatments. Vitamin deficiencies, especially a lack of vitamin B12, can also lead to numbness and can be treated with supplements.
In some cases, numbness in the head can be caused by nerve irritation or inflammation. Occipital neuralgia, a headache disorder affecting the occipital nerves, can cause numbness in the scalp. Treatment options include medications, steroid injections, and surgery, although some procedures can permanently deaden the nerve.
Furthermore, infections, tumours, and enlarged blood vessels can cause nerve pressure and lead to numbness. Conditions such as multiple sclerosis, Lyme disease, and carpal tunnel syndrome can affect the nerves and result in numbness. Treatment for numbness varies according to the underlying cause, and it is important to seek medical advice to determine the appropriate course of action.

Sleeping position can cause numbness
Swelling in the head muscles can be caused by occipital neuralgia, a headache disorder that affects the occipital nerves in the scalp. This condition can cause pain, sensitivity, and possibly numbness in the scalp. However, it is not confirmed if this nerve irritation can cause numbness in the head as a symptom.
Sleeping in certain positions can cause numbness in the hands, arms, and even the head. When sleeping, maintaining a static position for an extended period can cause stress and compression in the nerves, especially if it restricts blood flow to a nerve. This is more likely to occur if you sleep on your stomach, with your arms tucked under your body or hands under your head.
To prevent numbness caused by sleeping positions, it is recommended to sleep on your back or side with your head, neck, and spine in a neutral position. If you sleep on your side, placing a pillow between your knees can help align your back. It is also important to avoid sleeping with your elbows bent more than 90 degrees, as this can strain the ulnar nerve in the elbow.
If you experience numbness in your hands or arms, try changing your sleeping position, avoiding sleeping with your arms overhead or tucked under your body. You can also try gently moving your hands and fingers by stretching, shaking, or massaging them to improve circulation and stimulate nerve activity.
While numbness in the hands or arms due to sleeping positions is typically temporary, persistent numbness may indicate an underlying medical condition such as carpal tunnel syndrome, diabetic neuropathy, cervical spondylosis, or alcohol use disorder. If numbness persists, it is recommended to consult a doctor or healthcare professional for diagnosis and treatment.

Numbness can be a symptom of a stroke
Swelling in the head muscle can be caused by occipital neuralgia, a headache disorder that affects the occipital nerves. These nerves run through the scalp and irritation of these nerves can cause pain and scalp numbness. However, this is typically restricted to the scalp and does not cover the face or the area near the ears.
Numbness or weakness in the face, arm, or leg, especially on one side of the body, can be an indication of a stroke. This may be accompanied by other symptoms such as confusion, trouble speaking, difficulty understanding speech, sudden trouble seeing, walking, dizziness, loss of balance, or coordination problems.
If you or someone else is experiencing these symptoms, it is crucial to act quickly. The F.A.S.T. (Face, Arm, Speech, Time) test is a widely recognized tool to identify stroke symptoms. Ask the person to smile (F) and raise both arms (A) to check for facial asymmetry and arm weakness. Then, ask them to repeat a simple phrase (S) to assess their speech. If any of these tests indicate possible stroke symptoms, call for emergency medical services immediately (T). Time is critical, as treatments are most effective when administered within 3 hours of the first symptoms.
