Red and swollen pimples on the back can be caused by acne and folliculitis, which can be treated with topical medications and oral medication.
1. Acne: Acne can cause red pimples or hard bumps on the back. It can be treated with medications such as adapalene and tazarotene under the guidance of a doctor, and topical antibiotics such as mupirocin ointment and fusidic acid cream when the local inflammatory reaction is obvious. If necessary, oral doxycycline, minocycline, isotretinoin and other drugs.
2. Folliculitis: Red and swollen pimples on the back can also be caused by folliculitis. Bacterial infections can be treated with mupirocin ointment, fusidic acid ointment and other medications under a doctor’s supervision. Fungal infections can be treated with antifungal medications such as econazole cream and ketoconazole cream under doctor’s supervision.
Patients should follow the doctor’s instructions to use medication, not self-medication, so as not to cause discomfort.
