Paralized testicle post hernia repair

Hi, I had a left inguinal hernia repair done approximately 1 1/2-2 months ago.  After the surgery I noticed that my left testicle hund a lot lower than it did before and it was causing considerable discomfort.  i soon realized that I was able to draw up my right testicle at will but the left one would not move at all.  i brought my concern to my surgeon who said that some numbness is common and he wanted to see me in a month.  Well, more than a month has passed and there is still no movement in the left testicle.  My surgeon stated that it was possible that he may have cut a nerve.  My question is this.  I have spoken to my Primary Care Physician who stated that in all his years, he has never seen this in a post hernia repair.  I have done some reading on this and a sympton like mine was described and the cause was a severing of the nerve that runs down the spermatic cord.  Is there any other causes than that becuse that is irreversible.  Should I seek a neurologist, a urologist, or a lawyer!  Please help.  I'm terrified that this is going to be permanent.

Thanks

I had an inguinal hernia repaired by incision in 1993 at the age of 14 and the same thing happened, but I never reported it. I definitely cannot control my right testicle. I remember my right scrotum filled with a mass of hard scar tissue after the surgery, which subsided after a few days. The surgeon was not concerned about that. I don't know if it affected my fertility, as I have not had (nor tried to have) any children. It has not made me impotent though.
