Inflammation of the forehead skin may appear red and swollen, and may appear as flaky erythema with small papules, blisters, and elevated skin temperature, pain on pressure, and, if severe, generalized elevation of body temperature. Treatment requires intravenous penicillin sodium injection or intravenous clindamycin phosphate injection. After a few days, the color of the rash becomes darker, and most of the swelling subsides, you can change to oral minocycline hydrochloride capsules, or doxycycline capsules for antibacterial and anti-infection treatment. At the same time, you can apply topical Rafenolol solution 2 times/day, 20 minutes/times, and then apply compound polymyxin B ointment 2 times/day for treatment. During the treatment period, you need to avoid drinking alcohol, as well as consuming spicy and irritating food.
