How can I treat a rash on my back?
assistant
The first step in treating a rash is to identify the cause. Common causes of rashes include allergies, eczema, and infection. If you suspect an allergic reaction, it's important to avoid any potential allergens that may be causing your rash. You can also try over-the-counter antihistamines or topical corticosteroids to reduce inflammation. For more serious cases, it's recommended to consult a doctor for proper diagnosis and treatment.
