Itchy Neck

What is an itchy neck?

An itchy neck is a sensation on your neck that makes you want to scratch that area. The itchiness may be mildly annoying or severe to the point where it keeps you up at night. You may or may not have a rash, skin discoloration or other symptoms along with the urge to itch.

If you develop an itchy rash on your neck out of nowhere, you might be wondering what caused it and how to find relief. The good news is many of the causes are short-lived and easy to remedy.

For example, you might simply have dry skin and need to use a good moisturizer. Or maybe a soap, laundry detergent or necklace is causing irritation, and it’s simply a matter of switching to a different product.

Sometimes, chronic skin conditions — like various types of dermatitis — cause an itchy neck. The condition may cause itchiness on other parts of your body, too. Healthcare providers can treat skin conditions with medications.

If your itchiness persists, affects other areas of your body or causes you distress, don’t hesitate to reach out to a provider. They’ll identify the cause and help you feel better.

Why is my neck itchy?

There are many possible causes of an itchy neck that generally fall into these categories:

• Temporary skin irritations, reactions and allergies.
• Long-term (chronic) skin conditions.

Temporary skin irritations, reactions and allergies

Lots of things can disagree with the skin on your neck and cause itching. Here are some conditions that are usually temporary and easily treatable:

• Dry skin. Your skin needs enough moisture to feel soft and comfortable. When it doesn’t get the moisture it needs, it can feel dry, rough and itchy. You might get dry skin on your neck if you don’t typically apply moisturizer there or linger too long in a hot shower. Dry air in your home can also contribute to dry skin on your neck and elsewhere. Using skin care products that contain emollients can soothe your skin and relieve itching.
• Heat rash (prickly heat). This is a cluster of tiny pimples on your skin. The itchy rash forms when pores trap droplets of sweat. Heat rash can happen anywhere on your body, but your neck is a common location. You’ll have the urge to scratch your skin, and the itchiness may get worse if you keep scratching. Using calamine lotion (not powders or creams) can help soothe your skin and relieve discomfort.
• Contact dermatitis. This is your skin’s reaction to an irritant or allergen. You’ll develop an itchy rash that’s swollen, bumpy and discolored. Common irritants include soaps, synthetic fabrics, laundry detergents and hair dyes. Allergens include skin care products with fragrances and jewelry metals like nickel. All these things might easily come into contact with your neck. If you suddenly develop an itchy rash on your neck, ask yourself what’s different lately. Did you try a new body wash or perfume? Start wearing a new necklace? Don’t use the new item for a while and see if your symptoms go away. If not, then something else might be the cause.
• Head lice. This is when tiny insects (lice) take up residence in your hair. A head lice infestation causes intense itching on the back of your head and neck. This condition is most common among kids age 3 to 11 and those in their households. Medicated shampoos can get rid of the lice and clear up symptoms.
• Prurigo pigmentosa. This is often called a “keto rash” because starting a low-carb or keto diet seems to be a risk factor. Researchers are still learning the exact cause of this rash, but they believe ketosis is a likely trigger. Prurigo pigmentosa is an itchy rash that typically forms on your neck, chest and back. After several days to weeks, the itchy bumps crust over but leave behind darker spots (hyperpigmentation) that may last for months before disappearing. Your healthcare provider may recommend you resume your usual eating patterns if you develop this rash.
• Shingles. A shingles rash usually appears as a band of rashes or blisters on one area of your body — often on one side of your neck. Before the rash forms, you might feel pain, itching or discomfort in that area. Your provider can recommend medications to manage symptoms.

Long-term (chronic) skin conditions

Sometimes, your neck itches because of a long-term skin condition. You’ll probably feel itchy in other areas, too. The itchiness might catch you by surprise if you’re just starting to develop the condition.

At first, you might just think something irritated your skin. But persistent itching may disrupt your routine or keep you up at night. These are signs that you should see your usual provider or a dermatologist. They’ll diagnose the issue and suggest treatment.

When you can’t stop scratching your neck (and maybe other spots, too), here are some possible causes:

• Atopic dermatitis. Children and adults with this type of eczema may develop itchy, dry patches of skin on their neck and face. Researchers have identified head-and-neck dermatitis as a variant of atopic dermatitis because it affects these areas so often. You’ll likely have itching along with a scaly rash that’s red to brown. These symptoms may only affect your neck and face, or they may also affect other areas of your body like your hands, elbows and knees. Atopic dermatitis often begins in childhood but can appear for the first time in adults, too.
• Neurodermatitis. This type of eczema typically affects just one or two patches of your skin. These patches can be anywhere you’re able to reach with your hands, but your neck is one of the most common areas. Neurodermatitis causes intense itching, especially when you’re feeling stressed or trying to sleep. This condition can develop any time in life, but research shows it often begins between the ages of 30 and 50.
• Scalp psoriasis. Although “scalp” is in the name, this condition often affects surrounding areas like the back (nape) of your neck. It’s an autoimmune condition that causes thick, discolored patches of skin. Your skin will feel dry and itchy, and it may crack or bleed.

How is an itchy neck treated?

You don’t necessarily need treatment for an itchy neck. If your skin feels dry and you don’t have other symptoms like a rash or discoloration, you can apply a fragrance-free moisturizer. Be sure to choose a moisturizer that’s healthy for your skin. Try to avoid scratching your skin. Repeated scratching can cause your skin to break open and bleed. Broken skin also puts you at risk of an infection.

You may be able to manage contact dermatitis by avoiding the trigger — if you know what it is. If you don’t, your healthcare provider can help you identify it. Your provider may suggest a patch test (a type of allergy testing) to figure out the root cause of your symptoms. Meanwhile, you can manage the itching by:

• Applying a cold compress to your neck.
• Taking a colloidal oatmeal bath (colloidal oatmeal is a special, powdered form of oatmeal that you add to the water).
• Applying a medicated anti-itch cream, such as 1% hydrocortisone, which you can get at your local drug store or pharmacy.

You may need prescription medications (pills you take by mouth and/or creams you apply to your skin) to manage chronic skin conditions. Your provider will recommend the medications that are appropriate for your diagnosis.

If you have a chronic skin condition like eczema or psoriasis, ask a provider before using home remedies or any skin care products. Certain ingredients can worsen irritation or cause an allergic reaction. Your provider can tell you which ones to choose or avoid.

Can an itchy neck be prevented?

Here are some tips to help you prevent itchiness on your neck and elsewhere:

• Use a humidifier to add moisture to the air around you.
• Take warm (not hot) showers and limit each shower to five to 10 minutes.
• Apply moisturizer to your skin within a few minutes of bathing.
• Avoid skincare products that have a fragrance.
• Know what substances and fabrics irritate your skin or cause an allergic reaction. Avoid them whenever possible.
• See a healthcare provider regularly to manage chronic skin conditions.

When should I call a healthcare provider?

Call a healthcare provider if any of the following are true:

• Your itchy neck lasts longer than a couple of weeks.
• The itchiness keeps you up at night.
• Treatment makes your symptoms worse.
• Scratching breaks open your skin.
• You have signs of an infection. These include swollen skin, crusty skin texture and oozing pus. You may also have nausea, vomiting and/or fever.
• You develop a rash after recently starting a keto diet or making other changes to your eating patterns.

It’s also OK to contact your provider any time you have questions or concerns. Sometimes, all you need is peace of mind and reassurance that it’s nothing serious.

Is an itchy neck a sign of cancer?

Itchiness isn’t the most common symptom of cancer, but many people with cancer develop itchy skin at some point. There are many causes of itchy skin when you have cancer, including inflammation that occurs in response to cancer cells.

But keep this in mind: if only your neck is itching, it’s likely not due to cancer. Itching associated with cancer usually occurs all over your body. And there’s typically no rash. You’ll probably have other symptoms besides itching, like fatigue and low appetite.

If you’re concerned about any symptoms you’re experiencing, reach out to a healthcare provider.

Does scabies cause an itchy neck?

Scabies usually doesn’t cause an itchy neck in adults. Instead, the itchy rash forms on other areas like between your fingers and in the creases of your elbows and knees. Babies and young children may itch all over, including their necks.

A note from Cleveland Clinic

The shirt that looked so good in the window display? Your neck isn’t a fan. The lotion that smelled heavenly in the bottle? It’s setting your neck ablaze. We’ve all been there — things we look forward to wearing or using end up wreaking havoc on our skin. Your neck is especially vulnerable since it touches so many substances each day, often without you thinking twice about it. But as soon as that itch sets in, you can’t pull your attention (or your fingernails) away from your neck.

An itchy neck is common and often easy to manage. You might know the trigger, or if not, a little detective work might solve things. But if you can’t figure out why you’re so itchy, or the scratching is causing you serious distress, that’s a sign you need to call for reinforcements. Your healthcare provider can identify the cause and recommend the best treatment.
