What should I do if my toenail is growing into the skin, and what disease is this?
Ingrown toenails may be caused by paronychia and can be managed through general treatment, medication, physical therapy, etc.
1. General Treatment
If paronychia leads to an ingrown toenail, it is important to wear properly fitting shoes in daily life and avoid footwear that is too tight or ill-fitting. Additionally, keeping the toes dry and avoiding moisture buildup and sweat retention can help prevent infection.
2. Medication
Paronychia is a purulent infection of the soft tissue surrounding the nail, commonly caused by bacteria such as *Staphylococcus aureus*, which may result in the toenail growing into the surrounding skin. If there is any break in the skin on the toe, under medical guidance, hydrogen peroxide or iodophor can be applied or used for soaking the affected area. Topical antibiotic ointments, such as mupirocin ointment or erythromycin ointment, may also be used for treatment.
3. Physical Therapy
Under a doctor's guidance, physical therapies such as semiconductor laser irradiation or local helium-neon (He-Ne) laser irradiation may also be used to help reduce inflammation and promote tissue repair.
Additionally, surgical treatment is another option. If symptoms are severe or persist for a prolonged period, prompt medical consultation is recommended. A physician may perform relevant examinations to determine the underlying cause and recommend appropriate treatments, including surgery if necessary.
