I suffered from nerve damage for around five months. The pain was in my groin, it was caused by exercise, and it was excruciating.I spoke with a urologist, and he said that the pain was caused by an inflamed inguinal nerve.I researched the inguinal nerve, and discovered that it went from the spinal cord (L1, L4) to the groin area. I then had a chiropractor adjust those vertebrae, and the groin pain completely went away. So if you're suffering from nerve damage, rather than treating the pain, you might want to consider treating its source. It worked for me.
Hope this helps someone.
