If you’ve ever experienced a sensation where the top of your head feels cold, it could be a sign of an underlying health issue. While there are several potential causes for this symptom, some of the most common include sinusitis, paresthesia, or diabetes. Sinusitis is a condition where the sinuses become inflamed, causing a range of symptoms, including a feeling of pressure or pain in the forehead or top of the head. Paresthesia refers to a tingling or numb sensation in the scalp, which may feel like a cold spot. Diabetes can also cause cold sensations on the top of the head due to nerve damage. If you’re experiencing this symptom, it’s important to speak with a healthcare professional to determine the underlying cause and receive appropriate treatment.
Conditions that would cause cold spot
1. Paresthesia
Paresthesia is a medical condition that causes abnormal sensations in the body, including a cold spot on the top of the head. This sensation can be described as a feeling of coldness or numbness that is not relieved by applying heat or wearing warm clothing.
There are various conditions that can cause paresthesia, including nerve damage, circulation problems, and certain medical conditions. One common cause of paresthesia is nerve damage or compression in the cervical spine, which is the area of the neck that supports the head. Nerve damage in this area can cause abnormal sensations in the head, including the sensation that the top of the head feels cold.
Another possible cause of paresthesia is poor circulation, which can be caused by a variety of factors, including smoking, high blood pressure, and high cholesterol. Poor circulation can cause blood flow to the head to be reduced, which can lead to a cold sensation in the top of the head.
Certain medical conditions can also cause paresthesia, including migraines and multiple sclerosis. When the top of your head feels cold it could be a sign of a migraine, which can often cause a sensation of coldness or numbness. Migraines are severe headaches that can cause a variety of symptoms, including cold spots on the head. Multiple sclerosis is a chronic autoimmune disorder that affects the nervous system and can cause a variety of symptoms, including numbness and tingling sensations in various parts of the body, including the head.
In some cases, paresthesia may be a side effect of medication or a result of a vitamin deficiency. For example, vitamin B12 deficiency can cause nerve damage and lead to paresthesia in various parts of the body, including the head.
2. Sinus inflammation
Sinus inflammation, also known as sinusitis, is another common condition that can cause a sensation of a cold spot on the top of the head.
The sinuses are small, air-filled cavities located in the skull, and when they become inflamed, they can cause a range of symptoms, including nasal congestion, facial pain, and pressure, and a feeling of fullness in the ears. In some cases, sinus inflammation can also cause a cold sensation in the top of the head.
One reason for this sensation is that the sinuses are located close to the top of the head, and inflammation in this area can cause pressure and discomfort that can be felt in the scalp. Additionally, sinus inflammation can cause changes in blood flow to the head, which can cause a sensation of coldness.
Sinus inflammation can be caused by a variety of factors, including allergies, viral or bacterial infections, and structural abnormalities in the nasal passages. Allergies can cause inflammation in the sinuses, which can lead to a variety of symptoms, including a cold spot on the top of the head. Viral or bacterial infections can also cause inflammation in the sinuses, and may lead to a sensation of coldness in the scalp.
Structural abnormalities in the nasal passages, such as a deviated septum or nasal polyps, can also contribute to sinus inflammation and may cause a cold spot on the top of the head. In some cases, treatment for sinus inflammation may include medication, such as antibiotics or nasal sprays, or surgery to correct structural abnormalities in the nasal passages.
3. Diabetes
One of the main reasons why the top of your head feels cold is peripheral neuropathy, a type of nerve damage that affects the peripheral nerves, which are the nerves that transmit signals from the brain and spinal cord to the rest of the body. Peripheral neuropathy can cause abnormal sensations, including a cold spot on the top of the head, due to damage to the nerves that supply the scalp.
Peripheral neuropathy is a common complication of diabetes, and can be caused by a variety of factors, including high blood sugar levels, inflammation, and oxidative stress. Over time, high blood sugar levels can cause damage to the blood vessels that supply the nerves, leading to nerve damage and abnormal sensations.
In addition to peripheral neuropathy, diabetes can also cause changes in blood flow to the head, which can contribute to a sensation of coldness. High blood sugar levels can cause damage to the blood vessels, which can lead to reduced blood flow to the scalp and other parts of the body.
Other factors that can contribute to a cold spot on the top of the head in diabetes include poor circulation, vitamin deficiencies, and certain medications. For example, some medications used to treat diabetes can cause nerve damage, which can lead to abnormal sensations, including a cold spot on the head.
4. Injuries and burns
Injuries and burns can cause a cold spot on the top of the head due to damage to the nerves or blood vessels in the affected area. In some cases, the sensation of coldness may be accompanied by numbness or tingling.
One possible reason why the top of your head feels cold could be due to an injury is nerve damage. The nerves that supply the scalp can be damaged by a variety of factors, including trauma to the head, compression, or stretching. When these nerves are damaged, they can no longer transmit signals properly, leading to abnormal sensations like coldness.
In addition to nerve damage, burns can also cause a cold spot on the top of the head. Burns can damage the skin and underlying tissues, including the blood vessels that supply the scalp. When blood vessels are damaged, blood flow to the affected area may be reduced, leading to a sensation of coldness.
In some cases, a cold spot on the top of the head may be a sign of a more serious injury, such as a traumatic brain injury. Traumatic brain injuries can cause damage to the nerves and blood vessels in the brain, leading to abnormal sensations like coldness or numbness.
It is important to seek medical attention if you experience a cold spot on the top of your head after an injury or burn. Your doctor can assess the extent of the injury and determine the best course of treatment. Depending on the severity of the injury, treatment may include pain medication, wound care, or physical therapy.
5. Drug and substance abuse/medications
Drug and substance abuse or the use of certain medications can lead to a cold spot on the top of the head. This sensation may be a side effect of the substance or medication, or it may be a result of underlying conditions associated with drug abuse.
Drug abuse can cause damage to the nerves and blood vessels in the body, leading to abnormal sensations like coldness. Drugs like cocaine, amphetamines, and opioids can cause constriction of blood vessels, leading to reduced blood flow to certain areas of the body, including the scalp. This reduced blood flow can result in a sensation of coldness in the affected area.
In addition to direct damage to the nerves and blood vessels, certain medications can also cause a cold spot on the top of the head. For example, chemotherapy drugs used to treat cancer can cause nerve damage and peripheral neuropathy, which can lead to cold sensations in the scalp and other areas of the body.
If the top of your head feels cold, it could be caused by other medications such as antidepressants, antipsychotics, and medications used to treat epilepsy. These medications can affect the nervous system, leading to abnormal sensations like coldness or tingling.
