left testicular pain following hernia surgery

  Ever since I had a left inguinal hernia repaired about three years ago, I have had constant pain in my left testicleTesticle lump

Retrograde ejaculation has disappeared.  The ejaculate no longer shoots, it just sort of dribbles out, and the volume has decreased.  Sometimes the sensation of pain in the left testicleTesticle lump

  Since the hernia surgery I also have pain that radiates from the surgical area down the inside of my thigh to my kneeAnterior cruciate ligament (acl) injury

Dermatitis, herpetiformis on the knee
Knee arthroscopy
Knee arthroscopy - series
Knee joint replacement
Knee joint replacement prosthesis
Kneecap dislocation
Meniscus tears
Normal knee anatomy.  This has subsided somewhat but is still very noticeable and aggravating, following several injections of prednisone in the year after surgery.  As with the left testicle, sometimes this pain is also more noticable during sexual activity.
  My general health is excellent.  I'm 41, tall, normal bodyweight, athletic, don't smoke, only drink occasionally, and have never had a major illness,  but this problem with pain and performance is really getting me down.  I would do anything to have my body back the way it was before my hernia surgery.  Please help me, there has to be someone out there who can fix this.  Carl

Dear Carl:
Pain in the groin and testicular area is not very uncommon after hernia surgery, and can in some cases be attributed to involvement of a small nerve supplying these structures (the genitofemoral nerve). This nerve can be stretched, cut, ligated, or tethered at site of surgery, or get entrapped in scar tissue. The problem is often temporary, and in persistent cases can be treated with medications, nerve blocks, and even re-exploration for clearing the nerve from scar tissue.
Genitofemoral neuropathy, however, does not cause the ejaculatory difficulties. I do not have any obvious explanation for the symptom. Such difficulty can occur from certain drugs, some antidepressants (Prozac, Zoloft, etc) featuring high on the list.
You may benefit from a neurological and also a urological consultation.
