Sometimes there is a white cheese-like discharge from the coronal sulcus, accompanied by a foul odor. The inner plate of the foreskin and the glans also have an itching sensation, and the surface of the glans also has reddish pimples or red dots of varying sizes. Usually must open the foreskin for cleaning, keep the foreskin cavity clean and hygienic, can be used externally parexone ointment, once in the morning and once in the evening. If recurrent episodes, patients with long foreskin and phimosis are better to do circumcision.
