Within the last few weeks the veins in my scrotum and penis have been getting dark blue/purple and bright red causing dull pain and discomfort. I also am experiencing dull pain in the tip of my penis when it is erect and during sexual intercourse. My erection isnt as large as usual. I have also been experiencing other symptoms such as slight burning during urination, eye floaters, mouth ulcers, and poor blood circulation. I have a varicocele. I wonder if this could be the problem or if I am experiencing symptoms of some sort of infection. I have done blood and urine tests which both came back fine. Should I see a urologist? Has anyone experinced symptoms like this? Im 22 years old.
