Skin disorders that you may mistakenly think are urticaria
A quick Google search or self-diagnosis of a skin disorder is definitely not correct, and if you are not a dermatologist, the symptoms of some skin diseases are similar and can only be distinguished by an expert.
It is easy to confuse any skin disease with the red, itchy bumps caused by urticaria. Symptoms are general and relatively common among many skin disorders.
An outbreak of urticaria may seem like a bad thing at first, but it probably won’t last long: The condition may appear in the morning and then disappear completely by mid-day unlike other skin conditions, according to the Mayo Clinic.
Although tests are available to confirm urticaria, and antihistamines are readily available without the need for a prescription, diagnosis and treatment are still difficult.
So how do you know if you have urticaria or another skin disease or skin disorders?
In this report, we review 5 common skin disorders that closely resemble urticaria.
5. Heat rash
Heat rash causes raised red bumps, similar to those caused by urticaria, on the skin, but the swellings caused by heat rash are usually smaller than those caused by urticaria, and even look like small pimples.
It occurs when clogged pores (sweat ducts) trap sweat beneath the skin. Symptoms range from superficial blisters to stinging or intense itching, according to How Stuff Work.
Most heat rashes usually clear up within a couple of days when sweat is allowed to dry naturally with loose-fitting clothing and then taken off, and temperature controlled whenever possible.
You can apply a specialized fragrance-free moisturizer or “hydrocortisone” cream to calm redness, but you should avoid other types of lotions or ointments, because they irritate sensitive skin.
4. Contact dermatitis
Contact dermatitis is an itchy rash from direct contact with something allergic to your body, including soap, cosmetics, scents, jewelry or plants.
Its symptoms include: red swellings that can be confused with the symptoms of urticaria; However, the difference between them is that the symptoms of urticaria appear on multiple areas of the skin, while the rash caused by contact dermatitis appears only on the areas that have been exposed to the allergen.
Contact dermatitis lasts two to four weeks and usually clears up on its own.
Rosacea is a common skin disease like allergic urticaria. It causes redness of the skin and the appearance of capillaries, in addition to small red bumps filled with pus on the face. It is a chronic skin condition, which means that these symptoms may remain irritated for weeks and then fade.
Before rosacea symptoms appear, you’ll probably start to easily notice the redness on your face before it spreads all over the face, according to Healthline.
Unlike urticaria, which can affect different parts of the body, rosacea is limited to the face.
The cause of rosacea is still unknown, but it may have its roots in genetics with the environment, exercise performance, eating hot foods, exposure to sunlight, heat or stress.
There is no complete cure for the disease, but there are oral and topical medications known to reduce its severity, including those that target blood vessels and others that control blisters caused by a mild infection.
2. Eczema (atopic dermatitis)
Atopic dermatitis, the most common type of eczema, is similar to urticaria. It results in red spots and small bulges, in addition to itching and cracking of the skin. These symptoms often appear behind the knee, around the ankles and wrists, on the face, neck and upper chest area, and can also affect the area around the eyes, including the eyelids.
Unlike urticaria, eczema does not heal itself.
Although the actual cause of eczema is not known, it is believed to be related to dry, irritated skin as well as an overactive immune system, which can cause the body to trigger an allergic reaction in an unnecessary time.
It is also commonly associated with staphylococcus bacteria, which can exacerbate symptoms due to stress, sweating, dry skin, lack of hydration, cigarette smoke, certain foods, and wool or handmade clothing.
Eczema may look like urticaria on the surface, but the treatment is very different.
Treatment is limited to things that relieve the pain of eczema, including corticosteroid creams and antihistamines to relieve itching, reduce inflammation, and immune stimulants.
Light therapy is also known to be effective in dealing with eczema; Because ultraviolet rays can inhibit the inflammatory process.
1. Pityriasis Rosea
Pityriasis rosea, like urticaria and the other skin conditions on this list, begins with large, swollen red patches of skin. It may also be accompanied by headache, fever, sore throat and stuffy nose.
Initially, a telltale spot appears, and it is often confused with urticaria and alopecia. As the condition progresses, it spreads around the macula as small, scaly patches resembling a pine tree.
In fact, the cause of pityriasis rosea is unknown. In general, pityriasis rosea goes away on its own within 4 to 6 weeks, but in certain cases, the rash needs to be treated by a doctor.
