What Causes an Itchy Skin Rash on the Neck and Throat?
Most cases of a skin rash on the throat or neck are acute (short term). It may be due to an irritation from the fabric of your clothing (contact dermatitis) or a skin condition like hives (urticaria) and in some severe cases of acne, there may be some pimples on the neck which are itchy.
A chronic neck skin rash is more likely due to other causes. Being a ‘fold’ of the body, like the knees and elbows, chronic skin conditions like eczema tend to persist in these regions. While the neck or throat region is not a common site to be affected in eczema, it is still prone to these types of rash in a very allergic person.
Other possibilities for a neck or throat skin rash include a fungal infection of the skin, contact dermatitis due to the use of hair shampoos or dyes (which drip onto the neck or throat when bathing) as well sunburn or heat rashes. Many women who use skin lightening products for years will suddenly develop a rash on the bleached areas – the face and neck being the most common.
Not all skin rashes are itchy and if you find a slow growing rash developing on your neck that is not itchy, painful to touch or palpable (does not feel rough, smooth, raised or depressed) then it could be due to a pigmentation disorder like vitiligo or melasma.
In order to identify the cause of your itchy skin rash on your neck or throat, first identify the most recent change in your clothing, personal hygiene routine or grooming. Exclude any known or suspected triggers especially clothing made from synthetic fabrics or wool. Avoid applying perfume or scented creams on the neck or throat region.If your rash is persisting or symptoms are intensifying after a few days, then visit your doctor for further advice.
