Thanks Rich for your question.
The cause of  your pain could be as simple as dilated veins  around the testicle ( called a varicocele , which are more common on the left than the right) or as ominous as a testicular tumor.  This needs to be at least checked out by a physical exam from your family doctor if not a Urologist soon.  Other causes should be ruled out also like infection or a  benign epididymal cyst.  There is no way to be sure without an exam.  
Sorry I could not be of more help.  Please use the site search function and look up (epididymal cyst, testicular pain, testicular mass)  questions and answers for more information.
Good Luck
