This article discusses the possible causes of a neck rash and what you can do if you develop one.
Causes
A neck rash can develop for many reasons. Some of the most notable causes of a neck rash include:
Infections
Types of infections that cause neck rashes include:
Viral: Viral infections can sometimes lead to neck rashes. For example, a neck rash caused by COVID-19 may involve swelling, redness, and being warm to the touch. Other viral infections that may cause a rash on the neck include shingles, chickenpox, and measles. Bacterial: In some cases, a bacterial infection such as syphilis can cause a rash to develop and spread to the neck. Other bacterial infections such as impetigo, scarlet fever, and Rocky Mountain spotted fever are also associated with neck rashes. Fungal: Certain fungal infections have been shown to cause rashes in various areas of the body. If the fungus is on the neck, a rash can occur. Specific fungal infections that cause neck rashes include tinea versicolor or ringworm. Parasitic: Parasitic infections will cause a rash in various body areas, depending on where the parasite has infiltrated. One common parasitic infection that leads to a neck rash is scabies.
Allergies
Allergic reactions present differently depending on the type. If someone comes into contact with something they’re allergic to, such as cosmetics or nickel jewelry, they could develop a neck rash caused by an allergic reaction.
The symptoms that develop include redness, itching, and hives.
Serious Conditions
A neck rash could indicate a severe health condition. The most notable health disorder that can lead to rashes of the neck is diabetes.
Other conditions that can lead to neck rashes include:
Meningitis (swelling of membranes that protect the brain and spinal cord) Rheumatoid arthritis Petechiae, which is a rash that appears as tiny red pinpricks on the skin Purpura, which is a type of rash that develops as purple-colored spots on the skin
Petechiae and purpura are not typically severe conditions but can occur with a serious health issue such as lymphoma (cancer of the lymphatic system).
Skin Conditions
Skin conditions are often one of the most common reasons for developing a neck rash. Many skin disorders can lead to a rash on the neck, including:
Psoriasis Eczema Folliculitis Acne Rosacea
Symptoms
The symptoms of a neck rash will depend on what type of rash it is. The most notable symptoms of a neck rash include:
Redness Irritation or inflammation Skin that is warm to the touch Bumps, spots, or hives Intense itching Dry or cracked skin Pain
Diagnosis
Diagnosing a rash is possible through a rash evaluation. During the assessment, your healthcare provider will examine the rash and note any other symptoms you’re experiencing, either with the rash itself or those that may seem unrelated.

A rash evaluation may include:
An allergy patch test to determine if an allergen or irritant set off the rash A blood test to check for any signs of infection or illness A skin biopsy to check for skin disorders or infection
Treatment
Treating a neck rash depends highly on what is causing it. Allergy-driven rashes tend to clear up after you have removed the allergen. You can also treat them with antihistamines or topical creams to relieve symptoms.
If you have a skin disorder, you may need a specific treatment to help manage the rash. Many types, such as psoriasis and rosacea, are incurable. Typically, treatments for skin disorders include:
Topical corticosteroids UV light therapy (also called phototherapy) Topical drugs designed to suppress the action of the immune system Topical vitamin D3 analogs Topical benzoyl peroxide Topical antibiotics
In some severe cases, oral corticosteroids or immune-suppressing medications may be necessary. If an underlying health condition is causing the rash, that specific disorder will be treated. When that happens, the rash will likely clear up.
Prevention
Though there is not much you can do to prevent underlying health issues or skin disorders, you can prevent neck rashes driven by allergies or infection. You can do this by:
Avoiding others with contagious rash-causing illnesses Avoid allergens or irritants that you know cause a rash Use mild, scent-free soaps to cleanse your neck Limit your stress as much as possible
Summary
Neck rashes can be caused by various things ranging from infections to underlying health disorders. Skin disorders are often the most common culprit behind a neck rash. Pay attention to your symptoms if you notice a rash developing on your neck. Rashes can appear similar and be red and itchy and develop into bumps or spots. When you have a rash, it’s important to monitor symptoms and how long it lasts.
Not all rashes can be prevented, but those caused by allergies and infections can. To avoid a neck rash, you can stay away from allergens, protect yourself against infections, and maintain a good skin care routine.
A Word From Verywell
Having a new rash on your neck can be irritating for several reasons. The first is because of how it feels, and the second may be because of how it looks. No matter what, if you develop a rash, some type of reaction is occurring in your body. If the rash doesn’t clear in a matter of days, you should see your healthcare provider. They will get to the bottom of your neck rash so you can find out what’s going on and what you can do about it.
