Can paronychia with pus formation be treated by applying iodine tincture?
Disease description:
I didn't receive timely treatment when I developed paronychia on my finger, which led to pus formation. Can I treat the abscessed paronychia with iodine solution?

When paronychia has progressed to pus formation, iodine tincture can be applied for treatment, but proper application methods and precautions must be observed.
Iodine tincture is a commonly used skin disinfectant effective against various bacteria, fungi, and viruses, and it can help manage inflammation and infection associated with paronychia. However, because iodine tincture is highly irritating, excessive use may lead to local skin dryness or desquamation. Therefore, it should be used in moderation to avoid over-application. Before applying iodine tincture, the affected area should be cleaned with normal saline or benzalkonium bromide solution to ensure cleanliness. Then, using a cotton swab, apply an appropriate amount of iodine tincture gently to the affected site, taking care to limit the application area and avoid irritating surrounding healthy skin.
After applying iodine tincture, monitor changes in the condition. If symptoms such as redness, swelling, and pain improve, the treatment is likely effective. However, if symptoms continue to worsen or new complications arise—such as fever, chills, or other systemic reactions—prompt medical attention is necessary for professional treatment. While iodine tincture can be used to treat paronychia with pus formation, correct usage and adherence to precautions are essential to prevent excessive irritation and adverse reactions.
