Are the small red itchy spots on the body a sign of an allergy?

Small red spots accompanied by itching may indicate an allergic reaction, but they can also be caused by various other factors. During an allergic reaction, the skin may develop red spots and itching due to contact with or ingestion of certain allergens (such as foods, medications, pollen, etc.). Skin conditions or external irritations such as solar dermatitis, folliculitis, eczema, urticaria, and insect bites may also lead to similar symptoms. To accurately determine the cause, it is recommended to seek timely medical attention. A qualified physician can identify the specific cause through detailed examination and diagnosis, and provide an appropriate treatment plan. During the treatment process, self-medication should be avoided to prevent worsening of the condition or triggering other adverse reactions.
