I have high-flow priapism

High-flow priapism is a rare condition caused by increased blood flow to the penis, often following an injury. It usually isn’t painful but needs medical assessment to determine the best care.

What is high-flow priapism?

High-flow priapism is less common and usually not as painful as low-flow priapism or intermittent priapism. It often happens after an injury to the penis or the area between the scrotum and anus, which can affect how blood flows.

High-flow priapism usually doesn’t need emergency treatment because blood is still flowing through the penis. However, only a doctor can tell whether your priapism is low-flow or high-flow.

If you think you have priapism, contact a doctor immediately. Avoid trying any treatments at home, as they could make things worse.

Important: If you have heart problems, make sure to tell your doctor before starting any treatment.
