What should I do if many red spots appear on my back?

There are many red spots on the back, and the management depends on the specific cause: 1. **Identify the cause**: Determine whether the red spots are accompanied by symptoms such as itching or pain. They may be caused by allergies, folliculitis, heat rash (miliaria), eczema, etc. 2. **Maintain cleanliness**: Regardless of the cause, keeping the skin on the back clean is essential. Use mild cleansing products and avoid excessive rubbing or squeezing. 3. **Change clothing**: If the cause is suspected to be related to clothing material or tight-fitting garments, switch to loose clothing made of cotton or organic cotton to reduce irritation. 4. **Allergies**: Use antiallergic medications such as loratadine, cetirizine, etc. 5. **Folliculitis**: Apply topical antifungal medications, such as terbinafine or erythromycin ointment. 6. **Eczema, heat rash**: Apply topical corticosteroid creams, such as hydrocortisone butyrate cream. In severe cases, oral antihistamines may be taken. 7. **Seek medical advice**: If symptoms persist or worsen, seek medical attention promptly and follow the doctor's instructions for targeted treatment.
