What's the reason for hives occurring every few days?
Generally, recurrent urticaria may be caused by physical factors, psychological factors, infections, allergies, rheumatic fever, and other causes. The details are as follows:
1. Physical Factors
For example, cold or heat stimulation, sunlight exposure, and other physical triggers can lead to repeated episodes of urticaria. Untreated or inadequately treated cases may result in persistent recurrence of rashes. Medications such as desloratadine tablets or levocetirizine hydrochloride tablets can be taken under medical guidance.
2. Psychological Factors
Some individuals may experience flare-ups of urticaria due to emotional fluctuations or excessive mental stress. Patients are advised to maintain a positive mindset and ensure adequate rest.
3. Infection
Urticaria is a common skin condition, often triggered by bacterial or viral infections, which may cause recurrent symptoms. Treatment under medical supervision may include calamine lotion or loratadine syrup, which have antihistamine effects and help relieve discomfort.
4. Allergic Causes
Individuals with allergic constitutions may develop specific allergic reactions upon exposure to allergens, making them prone to urticaria. Common allergens include fish, shrimp, and crabs. Antihistamines such as cetirizine hydrochloride tablets or loratadine tablets can be taken orally under a doctor's guidance.
5. Rheumatic Fever
Urticaria associated with rheumatic fever is often related to a patient’s hypersensitive constitution. Timely treatment with antihistamines under medical supervision is recommended. Options such as loratadine tablets or cetirizine hydrochloride have anti-itching and antiallergic effects. In severe cases, corticosteroids may also be necessary.
In addition, urticaria may also be related to abnormalities in coagulation or immune function. It is important to visit a hospital for proper evaluation to identify the specific cause. Seek prompt medical attention if severe symptoms occur.
