Itchy Rash on Neck - Eczema or Psoriasis?

Itchy rashes on the neck may develop due to several reasons. They may be caused by an allergic reaction to food or hair dye, an insect bite, sunburn, or even acne. However, it may also be a symptom of skin disorders such as psoriasis or eczema. Millions of people in the United States suffer from these two conditions, which both cause an itchy and uncomfortable rash that does not seem to go away.

Both eczema and psoriasis may cause red, itchy, and scaly skin rashes. Although they are quite similar, their symptoms are usually different enough so your doctor can easily tell them apart even without diagnostic testing. To find out what kind of treatment or medication you need, you have to know the difference between these two conditions.

Eczema - causes and symptoms

Eczema, also known as dermatitis, commonly appears during early childhood or infancy. Irritant contact dermatitis, the most widespread type of eczema, usually develops when your skin becomes inflamed due to exposure to acids, soaps, detergents, and harsh chemicals. On the other hand, allergic contact dermatitis may occur if you have developed sensitivity to a substance such as metal and certain fragrances.

The common symptoms of eczema include red, itchy skin as well as tiny red bumps that feel rough when touched. Burning sensations and pain are also associated to both irritant contact dermatitis and allergic contact dermatitis. If you are suffering from the former, you may continue to experience itching and pain until you have discovered the cause and learned how to avoid it.

Psoriasis - causes and symptoms

Psoriasis is different from eczema because it is an inflammatory condition that is related to internal rather than external causes. The small percentage of patients suffering from psoriatic arthritis may also experience widespread pain in the joints. Its common symptoms include visible patches of indented red skin, bleeding or weeping when the scale crust is removed, and a thick coating of silvery scales.

Psoriasis is caused by internal inflammation but it may still be aggravated by external factors. Dyes, perfumes, and extreme heat or cold are only some of the factors that may worsen its symptoms. Constant scratching of the inflamed areas may also stimulate the growth of the silvery scales on the rash and make things much worse for the sufferer.

Now that you already know the difference between psoriasis and eczema, it will be easier for you to determine what type of treatment you need. The next time you experience itchy rashes on your neck, hands, or feet, you have to diagnose your condition before resorting to medicated baths, topical creams, or UV light treatments.
