Normally nail fungus is not amputated, even if it is severe. It is caused by an infection of the paronychial tissue, which is often the result of improper nail trimming, or squeezing of the nail. In more severe cases, there will be redness, swelling, pain, and oozing, but it usually does not lead to limb necrosis, so patients do not have to worry about amputation in severe cases of inguinitis. This can be dealt with in the general surgery department of the hospital, or the surgical surgery department, or the emergency department, usually under anesthesia at the root of the finger to incise the paronychial tissues, excise part of the nail, or remove all of the nail, and then carry out regular medication changes. In most cases the localization will heal completely in 1-2 weeks and the nail will grow out slowly. Therefore, after suffering from onychomycosis, you need to go to the hospital as soon as possible for relevant treatment. During the treatment period, try not to drink drinks containing alcohol, do not eat too spicy food, and can properly intake of fresh fruits and green vegetables.
