I've had 2 ingunal hernia repairs during army time 1971 and 1972. It was open surgery, 12 cm scar during local anesthesia and both felt terrible. It happened such that it was was several guys there + the professional surgeon and the students operated. At night I was bleeding much and was taken back to operation room for more suturing. That was a very unsuccessful operation on my left side. I became partly numb in my inner thigh and half leftside penis shaft, first super sencitive to later not have normal sensitivity, about half shaft and down on my ballsack. I have pain from the operation ever since that. In early 90s I had to correct it at our local hospital. Technics had improved a lot and I had epidural anesthesia (not sure about correct name in English). Operation vent well, I could see all in the reflection in the light armature. I was better, less pain and from the operation scar not much pain, but generally sore to stand up a couple of weeks after. Still have pain on my left side due to the bad first surgery! 1972 the professor surgeon operated my right side. Making the local anestesthesia was terrible painful and pain during operation too. Else it was successful. No nerve damage and some pain after and walking little bent forward. When healed it was just perfect. Don't feel anything at all of it, I shouldn't know it was done if I couldn't see the scar left. So it can be good and bad. But I think technics has improved a lot since my surgeries. I've suffered from very much pain since my first operation because I had the bad luck to be the test patient for surgeon students! That's just my story!
