i didn't notice any nerve pain, but u can check my previous posts of how i felt,
basically the first couple of days were weird, especially at night. just weird sensations in different parts of body, especially left leg . weird emotions, anger and fear mixed. but only did it for 5 days total. i think ur supposed to do it for 10, but i wanted to be cautious.
im probly gonna do nother round of przi soon. ive been seeing cercaria which im not sure if that is a normal stage or if its when the parasite gets stressed and decides to encyst. not even sure what parasite its from, but im thinkin some kind of fluke.
hope that helps =]
