Burning after Orchidectomy

[JMC935]

Had Testicular Cancer (Embryonic Carcinoma) in left testicul back 1995.  Doctor performed left Orchidectomy, then typical chemotherapy.  I am fine and healthy.  However, I have been complaining of a bad burning sensation in what seems to be the remaining vas deferens.  The sensation is as if the vas deferens fills up with very hot fluid just as I ejaculate and even sometimes as I am finishing urinating.  Approx. 1996, I had asked the original doctor about this and he explained it as Phantom Pains.  This has been going on now for 14 years and I can not get an answer from a doctor who can explain any possible reason for this burning sensation.  It does not happen every time I pee or ejaculate but I bet it happens a few times a month.  Is there any way any part of the area where the left testicul was could have a bad burning sensation during these activities?  This could range from nerve ending or vas deferens damage or any possibility that the vas deferens re-opened up and in some way is allowing fluid of any type to get in it and causing this discomfort?
