The foreskin tether is rich in nerves and blood vessels, so if there is an associated lesion at the foreskin tether, it may cause pain. Common causes: 1. Circumcision, local redness and swelling can occur, leading to pain at the foreskin tether, further aggravation of inflammation, and also changes such as erosion, exudation or rupture of the foreskin, all of which can aggravate the pain at the foreskin tether. Local redness and swelling with erosion and exudation can be seen during physical examination. The patient with a short circumcision can experience pain at the circumcision ligament after erection, and a downward curvature of the penis can be observed in the non-erect state, requiring surgical correction. 3. This part is a more sensitive part, and the nerves are widely distributed, so the pain is also more obvious.
