After a nail is pulled, you can touch water for about a month after a nail infection. Nail fungus is very common and is a purulent infection in which the nail and surrounding skin becomes red and swollen and the patient feels pain. If the inflammation progresses further, an abscess may form, and the pain and redness may expand, and when palpated, fluctuations may be felt. After the diagnosis of nail infection is confirmed, anti-inflammatory treatment, such as oral antibiotics, is required, and nail extraction is necessary to reduce the irritation of the nail to the nail groove and to promote the reduction of inflammation. After the surgery, the wound needs to be disinfected and changed regularly to promote healing, and the wound will heal in about a month, so you can touch the water.
