I recently noticed that I didnt had any morning woods and not getting proper erections and so thought of consulting an urologist. The urologist asked me to take USG scrotum and penile screen. The Radiologist injected 2 vials of Papaverine 30 mg/ml directly into penis intracavernosally to stimulate an erection for checking the blood flow. I had priapism with pain, later doctors treated me with blood aspiration and irrigation with saline. I had edema in the penis, which lasted for about a week. I felt pain when the edema was reduced by 80%, I coupd barely move. Now the edema was gone. But i still have pain and the penis has not returned to normal size, even after a week. My question is, 1) Is papaverine recommended for use in 22 year old male,even if its for diagnostic reasons? 2) How long does the edema usually last after priapism? 3) is it normal to have pain after the edema is gone? If so what can I do to reduce the pain? 4) Why the penis hasnt returned to the normal size?
