Large, hard red bumps appearing on the body during summer

Red, hard bumps appearing on the body during summer may be caused by insect bites, acne, or boils, and treatment should be based on the specific condition. Details are as follows:

1. Insect bites

In summer, there are more insects, and spending time outdoors frequently can lead to insect bites, causing itchy red swellings on the skin surface. It is advisable to apply medicated oils such as wind oil, floral water, or cooling oil according to medical advice to relieve itching.

2. Acne

In summer, the skin tends to produce excessive sebum. If proper skin cleansing is neglected, pores can become clogged, leading to conical papules accompanied by pain. Under a doctor's guidance, medications such as isotretinoin erythromycin gel, tretinoin cream, or adapalene gel may be used for treatment.

3. Boils

Boils occur when hair follicles or surrounding tissues are infected with Staphylococcus aureus, resulting in red, swollen, hard nodules on the skin surface, often accompanied by significant pain. Treatment may include topical antibiotics such as mupirocin ointment, fusidic acid sodium ointment, or erythromycin ointment, used as directed by a physician.

In addition, red bumps on the skin could also result from folliculitis, urticaria, allergic dermatitis, or other causes. Patients are advised to visit a hospital for proper diagnosis and targeted treatment.
