Nails that have grown into the flesh usually belong to ingrown nails, which can be relieved by soaking feet in warm water, medication and surgery. 1. Soaking feet in warm water: If the nail is simply overgrown and has not yet broken through the skin into the body, but only localized redness, you can soak your feet in warm water for 10-15 minutes each time to soften the nails and then cut off the nails, and apply iodine vodine or pilomoxetine ointment around the nails after trimming them to prevent infection. 2. Medication: If the toenail has already damaged the skin of the toe, it is necessary to take oral antibiotics to fight infection, and at the same time, it can be combined with 0.5% neomycin ointment and other drugs for external use. 3. Surgery: If the nail is deeper into the skin and causes onychomycosis, surgery is needed as soon as possible to remove the toenail that has entered the skin, thus achieving the purpose of treatment. In daily life, choose the shoes that fit well, avoiding the toenail compression due to the shoes are too tight; trimming toenails should be rounded and smooth, to prevent overgrowth of sharp nails; it is recommended that after the patient’s nails grow into the flesh, he or she should cooperate with the doctor to standardize the treatment in his or her own situation, and should not blindly use medication.
