Paronychia, characterized by redness, swelling, and pain, can be treated by applying iodine tincture for local disinfection and cleansing, which helps reduce swelling. Under a doctor’s guidance, anti-inflammatory ointments such as compounded polymyxin B, fusidic acid cream, or mupirocin ointment can also be applied. For severe redness, swelling, and pain, oral antibiotics may be administered in conjunction with the treatments mentioned above to reduce inflammation. It is important to follow a medically supervised and proper regimen when using antibiotics and to increase water intake during treatment. If the paronychia is caused by an ingrown nail piercing into the nail fold, trimming the nail may relieve the local swelling and pain. It is recommended to seek treatment at a professional hospital. Paronychia is a common condition, and taking preventive measures can help avoid its onset.
