Coronal groove has white dirt to still itch glans has small red dot is what disease

White dirt and itching in coronary sulcus and red spots on glans may be caused by balanitis.

Under normal circumstances, if men fail to maintain good personal hygiene, white dirt may exist in coronary sulcus due to local secretions that cannot be removed in time. At the same time, the dirt continuously accumulates in coronary sulcus, promoting the continuous breeding of local pathogens, which is easy to form infection and cause inflammation. At this time, patients are prone to symptoms of red spots on glans due to local inflammatory factors that continuously stimulate the skin layer.

It is recommended that patients can undergo medical examination to determine the cause and then carry out targeted treatment.
