When you mention "blisters", people think of spring and allergies. The medical name for "blister" is hives, which is a fairly common skin condition and 15-20% of people have at least one episode of hives in their lifetime. As a rule, if rash recurs for more than three months, it is called "chronic urticaria".
Urticaria has a certain relationship with seasons or solar conditions, and can also occur all year round. It is manifested by local swelling of skin and lumpy bumps that turn red. In medicine, it is called a "blister". Often has an itching sensation. The number and size of lesions are variable. Leaving no traces, it arises and recedes with time. time, repeatedly, sometimes several times a day, and course of disease can be long or short, from several days to several years or even more than ten years.
As for possible causes of hives, sometimes doctors cannot give an exact answer. Since etiology of urticaria is complex, about 3/4 of patients cannot find a cause, especially in patients with chronic urticaria, course of disease can last several years.
Common pathogenic agents include drugs such as antibiotics, food and nutritional supplements, mainly animal protein products such as fish, shrimp, crabs, meat, eggs, etc., dyes, seasonings, preservatives, etc. added to food, etc. can also cause hives; inhalation of pollen, animal dander, feathers, dust, cosmetics, formaldehyde gas, etc.; various infections can cause hives, including bacterial infections, viral infections, and parasitic infections; physical factors such as various irritants such as scratching, cold, heat and sunlight can be caused by mental stress, emotional arousal, menstruation, pregnancy, etc. can also cause diseases, many patients with internal diseases also suffer from hives.
The cause of hives is different for different people, and preventive measures are also different.
Regular daily life Traditional Chinese medicine emphasizes "conformity between man and nature", which means that people's rules of life should adapt to changes in external environment. get up, and in winter you should go to bed early and get up late; when four seasons alternate and climate changes dramatically, try to avoid intrusion of wind, cold, rain, heat, sun, dryness, humidity.
Keep house clean and keep fewer cats, dogs and other pets in house, because hair, dander, urine and feces of cats, dogs and other pets can cause allergies in humans, which is an important factor in inhalation allergies; clean your home more often and use carpets less, because house dust often contains dust mites that are invisible to naked eye. If they are inhaled along with dust, they often cause allergies without being aware of it. Also, allergy sufferers should go to park less and try not to grow flowers at home to avoid pollen-induced allergies.
Less contact with allergens. Patients in whom contact may cause hives should use less soap containing fragrances, avoid contact with rubber, hair dye, and other chemicals, or wear gloves when touching these items.
Quit smoking and give up alcohol Do not drink alcohol, including wine and beer, not to mention smoking. Not only are smokers themselves prone to allergies, but passive smokers such as their children can also be allergic.
One of causes of hives is related to eating habits. Certain foods can be triggers for hives, but foods that everyone should not eat are different and only a general range is mentioned here. Patients who do not have obvious stimuli or are still in onset period should, if possible, avoid "fats" and nutritional supplements.
The so-called hair products refer to products that cause disease, spread poison, and help fire and evil, which can easily cause old diseases and aggravate new diseases.
Patients with urticaria should eat more fresh vegetables and fruits and easily digestible foods. Fresh vegetables and fruits are rich in vitamins, especially vitamin C, which can reduce vascular permeability, reduce exudation and local swelling, and help reduce symptoms of hives. Eating too much protein at one time, drinking alcohol at same time, or eating irritating foods such as too acidic and too spicy will greatly reduce digestive function of gastrointestinal tract and food will not be fully digested and spoiled. into peptone or polypeptide and absorbed into body, increasing likelihood of allergies.
If this symptom still bothers you after avoiding allergens, you may want to see a doctor. I believe that with combined efforts of you and your doctor, your spring should be bright.
