I had the same surgery done in December. I can say I had very little pain as compared to the inguinal hernias I had repaired in the past. I took Bromelain supplements (before and after surgery) and they seemed to help with healing. Hope this helps!
I would also recommend Dr. Crisler's and Jay Campbell's books. I have read them both and they both provide valuable information.
Another book I read that I enjoyed and would recommend is "The No-Nonsense Guide to Testosterone Replacement Therapy" by Bill Hamzi.
