What are the red bumps on my arm?
The appearance of red bumps on the arms can be confusing and unsettling. This phenomenon may arise from various causes, such as insect bites, eczema, or allergic purpura. To ensure health, it is advisable to seek medical attention as soon as possible for examination and targeted treatment based on the specific cause. Timely diagnosis and management can help alleviate symptoms and prevent further health issues.
1. Insect Bites: In hot summer, insect bites are common. After being bitten by mosquitoes or other insects, the skin surface may develop red, small lumps accompanied by itchiness. Typically, no special treatment is required for this situation; just be careful to avoid scratching to prevent infection. If the itchiness is unbearable, some anti-itch creams can be used to relieve discomfort.
2. Eczema: Eczema is a chronic inflammatory skin disease that may be related to genetic factors or environmental influences. It usually manifests as papules and vesicles with exudation and erosion. For eczema, doctors may recommend topical medications like calamine lotion to relieve discomfort, along with oral anti-allergic drugs such as loratadine tablets to improve the condition.
3. Allergic Purpura: This skin disease is often caused by abnormal immune system reactions after exposure to pollen or animal fur. It mainly occurs on the limbs, especially the lower limbs, presenting with hemorrhagic spots or ecchymoses. Treatment involves using antihistamines, such as cetirizine hydrochloride capsules or chlorpheniramine maleate tablets, under a doctor's guidance.
4. Other Causes: Red bumps on the arms may also be related to urticaria, an acute skin reaction caused by external stimuli, manifesting as wheal-like changes. Urticaria treatment may involve taking anti-allergic drugs like ebastine tablets or desloratadine disodium tablets under a doctor's supervision.
In daily life, maintaining good personal hygiene habits is crucial for preventing skin problems. Dietary choices should focus on light and easily digestible foods, with an emphasis on fresh fruits and vegetables to supplement the body's nutritional needs. Additionally, maintaining a good mindset can help improve immunity and reduce the occurrence of skin issues. I hope these suggestions can help you achieve healthier skin.
