What happens when the coronary sulcus becomes black and what should I do?

Blackening of the coronary sulcus is generally caused by inflammation and infection, and it is necessary to go to a regular hospital for relevant examinations.

Blackening of the coronary sulcus may be caused by inflammation of the glans. Repeated stimulation of inflammation may lead to local congestion and blackening symptoms. For example, frequent sexual intercourse and excessive friction may cause local blackening, which requires taking sodium fusidate ointment, erythromycin ointment and other drugs under the guidance of a doctor for treatment.

During the treatment period, patients should strengthen personal hygiene care and wear loose and pure cotton underwear to reduce local friction. They should also go to the hospital for regular check-ups to observe the recovery of the body at any time.
