Symptoms of urticaria

In recent years, various diseases have appeared in people's lives, among which minor illnesses are the most common. Don’t ignore these minor illnesses, as serious illnesses often develop from minor illnesses. Skin disease is a general term for common diseases. Skin diseases are divided into many categories, that is to say, diseases related to the skin can be collectively referred to as skin diseases. Skin diseases have many causes, and most skin diseases require a long time to be effective in treatment.

Ordinary people often change the names of some diseases into more popular names. Urticaria is the common name for urticaria. As we all know, urticaria is a common skin disease. Patients will have red areas on their skin, and the disease is also easily contagious, so many people are afraid of this disease. So what are the symptoms of urticaria? Let’s talk about it today.

The basic lesion is the appearance of wheals on the skin. The skin often itches first, followed by the appearance of wheals, which are bright red or pale, skin-colored. A few patients have edematous erythema. The size and shape of the wheals vary, and the onset time is uncertain. The wheals gradually spread and merge into sheets. Due to edema of the dermal papillae, the openings of the epidermal hair follicles can be seen sunken downward. The wheal lasts from several minutes to several hours, and in some cases it can last for several days before disappearing without leaving any trace. The rash occurs repeatedly in batches, mostly in the evening. Wheals are often generalized but may also be localized. Sometimes it is accompanied by angioedema, and occasionally bullae form on the surface of the wheal.

Some patients may experience nausea, vomiting, headache, head swelling, abdominal pain, and diarrhea. Severe patients may also have systemic symptoms such as chest tightness, discomfort, pale complexion, accelerated heart rate, weak pulse, low blood pressure, and shortness of breath.

A disease that is cured in a short period of time is called acute urticaria. If the urticaria recurs at least twice a week for more than 6 weeks, it is called chronic urticaria. In addition to the common urticaria mentioned above, there are also the following special types of urticaria.

1. Skin scratch urticaria/artificial urticaria

2. Delayed dermatographism

3. Delayed pressure urticaria

4. Cholestatic urticaria

5. Cold urticaria

6. Solar urticaria

7. Contact urticaria

In addition, there are rarer types of urticaria such as heat urticaria, exercise urticaria, tremor urticaria, aquagenic urticaria, adrenergic urticaria, and electrical urticaria.

The above are the symptoms of urticaria. You can see that there are many classifications of urticaria, so after you get the disease, you must not blindly treat it yourself. You must first figure out which type of urticaria you have, and then treat it according to the doctor's advice. During treatment, you should also pay attention to physical hygiene and dietary taboos.
