Any clinical studies to support your claims, or are they just claims?
I'm basing my statements on clinical studies done on post abdominal surgery patients. I'm not just pulling it out of my ass. Regardless, fasting isn't going to help this condition, and the sooner the OP looks into neuropathic pain medication, the better off they'll be. Fasting just isn't going to solve this problem, sorry. Neuropathic pain has specific generators in the body and fasting won't do it. But you have a nice day now.
