The purpose of circumcision surgery is to remove the overgrown foreskin and expose the glans. Since the condition of each patient is different, different side effects can occur after the surgery, as follows: 1. Different degrees of foreskin edema, the degree of swelling is different for each patient, some degrees are light, some degrees are heavy. The majority of penile edema can disappear slowly after a period of time, so do not be too nervous; 2, some patients will complain of local urethral stinging pain when urinating after surgery, the majority of the symptoms appear within a short period of time, that is, within a week after surgery. Basically, with the extension of time, the glans and urethral orifice slowly adapt to air stimulation, this situation will gradually disappear, so do not worry too much; 3, the appearance of the penis after surgery may not reach a satisfactory degree, because the inner or outer plate reserved for each patient requires different circumstances, but will do their best to achieve the results that patients want.
