What to do if you have red and swollen pimples on your back

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.
