Penile veins are usually associated with the thinness of the skin on the surface of the penis, and if they are accompanied by painful symptoms, we need to be vigilant against diseases such as microangiomas. In normal people, the skin on the surface of the penis is relatively thin, and the blood vessels under the skin are relatively obvious when the penis is engorged with blood and in the state of erection, so that obvious veins can be observed, and this situation is a normal physiological phenomenon. If the penile veins in the raised state accompanied by pain symptoms, the clinical consideration may be the existence of hardening of the penile blood vessels or small hemangiomas, local blood circulation is not smooth. In this case, it is recommended that people should go to the reproductive department of the hospital, through the vascular ultrasound to observe the blood flow situation, and treatment.
