Three months after circumcision, painful local scars need to be examined at the hospital to find out whether there is hyperplasia of the local scars, painful nodules, or whether there is subcutaneous infection. Further treatment will be based on the examination: first, patients with scarring can develop local scar hyperplasia, which can cause foreskin contraction when the scar is hyperplastic. This can lead to scarring of the prepuce, which can nestle the glans and cause localized pain, requiring a hospital examination. If the presence of scarred prepuce or scarred foreskin stenosis is confirmed, a second surgery to remove the scar will be considered. Second, local pain can occur if the materials used during the surgery are not dislodged, such as the nail of the anastomosis is not dislodged or the residual wired knot in the foreskin, causing a reaction to the drainage line. It is necessary to go to the hospital for relevant examination to find out whether it is a dislodged wire knot or an un-dislodged auxiliary device, and if so, further removal is required. Thirdly, local scar formation, associated with neuropathic painful nodules manifested as pain, confined to a certain point can be considered to use symptomatic pain relief medication. However, medication is not effective and excision of the painful nodule is required.
