Testical pain

  my problem started with lower back pain.
  i went to my primary care phys. and was given 'naproxen' for possible musle spasms.  after taking the medication for four to five days, my back improved, but i cbegan to get a lot of movement in my left testical, and some pain (my right testical is undescended)  upon a papable exam my dr. had an ultrasound arranged, everything appeared normal.
  i stopped taking the medication and the pain stopped, but my back pain began again.  i started on the medication again, and my back is beginning to improve, but i am having paim in my left testical again.
  oh, and i do have a appointmet to schedule either removal or lowering of my right testical.  there is a chance it was forced up there via a bike accident as a kid.  the dr. said that he would be able to tell and make the necessary decision during the operation.
  do i have anything to be concerned about?

Dear Dave:
Testicular pain may radiate up the groin and into the abdomen or back.  Likely, pain from other sources such as a kidney stone may radiate to the testicle.  Therefore, it is difficult to isolate the source of testicular pain just on the basis of this internet exchange of information.  However, some common etiologies that arise from the testicle include trauma to the testicle, epididymitis (infection and/or inflammation of the epididymis), orchitis (infection and/or inflammation of the testicle), testicular cancer/mass, and intermittent torsion (twisting and untwisting of the testicle around its blood vessels causing decreased blood supply and pain).  I cannot identify the source for your left testicular and back pain on the basis of the given information, but agree that it is appropriate for you to undergo either right orchiectomy (removal of the testicle) or right orchiopexy (bringing the right testicle down) at this time.  
I would recommend that you follow up with your urologist in trying to identify the source of the pain, and keep in mind that the source may be entirely non-urological such as a muscle spasm, etc.  Also keep in mind that any surgical procedure to relieve pain only has a 40-50 percent chance of alleviating the symptoms of pain.  Although the surgical procedure mentioned above for your right undescended testicle would be necessary regardless of whether you were experiencing pain.  Wish you the best
