blue/grey penis

What are possible causes of a  blue/grey color of a head of a penis after a  3-5 mile jog? The color will stay for approx. 1/2 hour after jogging. The head will also be very cold. I feel this is some type of circulation problem and jogging for 20-30 minutes without circulation scares me, the color is quite dark. My doctor had me take 400 mg of vitamin E and drink water before the jog but it did not help at all, I tried this for a month. I am 54 years old and have been jogging for years.

Hello - thanks for asking your question.

With a dark color that clears 1/2 hour after jogging, there is a possibility of blood flow deficiency.

It is possible that this may be related to a circulation problem.  If you have diabetes, smoke, have high cholesterol or peripheral vascular disease, you will be prone to circulation deficiency.  You may want to discuss the option of an angiographic study, plethysmography (the measurement of volume change in an organ or limb) or ultrasound to evaluate for circulatory disorders.

Vasospasm of the blood vessels could also affect blood flow to distal organs.  

Another possibility could be a mass that may be obstructing blood flow.  To test for this, imaging would need to be performed - either an abdominal/pelvic CT scan or ultrasound.  

A referral to a urologist or vascular surgeon would be reasonable for further evaluation.  After they examine you, discuss the utility of imaging or testing for vascular disease.

Followup with your personal physician is essential.
