neuralgia
"I had  pains in my legs after knee surgery and I took this medicine only one pill 4 times in two days and I have never been so sick in my entire life! I was so sick to my stomach that even water made me even more sick. Whatever I ate or drank would come back up about an hour later. I could barely stand up straight, I was shaking, I had fever and chills, etc. It was horrible! I stopped taking it as soon as this started and then it took another two days to actually completely get out of my system!"
