Only one patient of his posted about her surgery and then left the forum before we could get more information from her. The Nantes team have a better long term record in the PN community, I think. I would stick to your plans. You will be in good hands.
Athlete until pain started in 2001. Diagnosed with PN in Nov. 2010. Probable cause: 3 difficult labors, 5 pelvic surgeries for endometriosis, and undiagnosed hip injuries. 60% better after 3 rounds of shockwave therapy in Cornwall, Ontario (Dec - Feb/12). 99% better after bilateral hip scopes for FAI and labral tears (April and July/12). Pelvic pain life coach Lorraine Faendrich helped me overcome the mind/body connection to chronic pain: http://www.radiantlifedesign.com
