The nails of the hands or toes turn gray or yellow, and the nail plate becomes thickened and brittle, or the middle layer of the nail plate is hollowed out or the nail edges are uneven. This is a nail disease caused by a fungal infection called onychomycosis, and most onychomycosis comes from ringworm infection. Because the nail plate is dense, it is difficult for topical medications to penetrate the nail, making ringworm one of the most stubborn and difficult to treat of the various ringworm diseases. Trauma, nail fungus, flesh spurs, and pregnancy are often the main triggers for onychomycosis. The dermatology department of the Dushanzi People’s Hospital in Karamay, Xinjiang, is not necessarily a case of onychomycosis, but only a combination of a history of tinea pedis or laboratory tests can confirm whether or not you have onychomycosis. Nail fungus should be treated patiently and thoroughly, and it takes about 100 days for hand nail fungus and 200 days for foot nail fungus. The Internet is developing rapidly and is profoundly affecting every aspect of our lives. Internet medicine can enhance the efficiency and value of medical services through the Internet, and as a medical practitioner in dermatology, I would love to provide services to you on this online platform.
