When to see a doctor
If you have an erection lasting more than four hours, you need emergency care. The emergency room doctor will determine whether you have ischemic priapism or nonischemic priapism.
If you experience recurrent, persistent, painful erections that resolve on their own, see your doctor. You might need treatment to prevent further episodes.
