The entire cost of nail extraction for nail infection is 150-200 RMB, and the cost of nail extraction at a tertiary hospital in Guangdong Province is 80 RMB per site. Before nail extraction, local anesthesia must be given, and the cost of local anesthesia is 25 RMB per site, plus local anesthetic medication and antibiotics for 2-3 days after the surgery, so the whole cost is between 150-200 RMB. However, for the first 3-5 days after nail extraction, it is recommended to go to the hospital every day to give a regular change of medication, disinfection, and bandaging, because this is the way to deep disinfection.
