Hello. It has been confirmed that I have varicocele in my left testicle. I initially went to the doctor because I have a sensation like ants crawling on my leg at the exact time of ejaculation and this sensation although not painful, per say, but uncomfortable and clearly not right ends right when the sperm actually begins to come out. Could this be due to varicocele or is something else going on. My primary as well as the specialist I was sent to (who confirmed varicocele) do not seem to know what the cause is.
