Toenail growth into the flesh is painful and suppurative, considered to be bacterial infection caused by nail infection, clinical treatment usually includes conservative treatment and surgical treatment two ways. If the abscess forms and conservative treatment fails, surgical treatment is needed: 1. Conservative treatment: If the pus is small and the pain is relatively small, you can apply iodophor after cleaning and then apply topical Chinese medicine such as ichthyolite ointment, gold powder, or antibiotic ointment such as mupirocin ointment and fusidic acid cream, as well as oral or intramuscular antibiotics for anti-infection treatment, usually 2-3 days. 2.Surgical treatment: If the abscess is large in scope or cannot be relieved by conservative treatment, surgical incision and drainage is required. It is necessary to remove a part or even the whole toenail and drain the pus adequately, and change the medication regularly to prevent reinfection after surgery. In chronic cases of recurrent nail infections, surgical removal of the recurrently infected toenail and surrounding tissue is required. Patients with simple onychomycosis should take good care of their feet on a daily basis, keep them clean and dry, and avoid using toenail cosmetics, and they will not recur. Patients with ingrown toenails, which are toenails that tend to grow into the flesh, are more likely to have recurrent nail infections and should pay more attention to properly trimming their toenails and wearing shoes that fit their feet.
