Priapism is a long-lasting erection of the penis that is not caused by (sexual) stimulation. The condition is rare and painful, and is usually the result of a sudden, inexplicable halt in the outflow of blood from the erected organ (penis). However, it may also be a consequence of a disease or nerve injury in the spinal cord, which governs erection.
Regardless of the cause, priapism is a serious condition; if an abnormal erection lasts longer than 3 to 4 hours, tissues (in the organ) can be permanently damaged and thereby permanently disabling erection.
What to do?
If you have a painful erection that lasts for no apparent reason, do not waste time trying to get rid of the condition with cold shower or some other ”home” measures, but immediately go to the nearest hospital.
Priapism is a condition that requires urgent intervention, and the only solution is an operative procedure that involves bypassing the clogging and thus allowing the blood to go away from the organ and return to the bloodstream. The wound usually heals after a few days and – if the surgery is performed on time – the patient will have normal erections (after some time).
