Thank you, I am seeing my doctor next week and will ask if I can have these investigations done
Hello,
If you are having a cold sensation in the penis then any nerve problem and vascular supply to the penis should be checked. I would suggest you to consult a urologist and get an ultrasound done. Other investigations which can be done are MRI or a cavernosogram (a test where a thin hypodermic needle is inserted into one area of the penis before a radio contrast solution is injected and X-rays taken).
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
