Question: 1. Ayone have success with Tylenol PM ? 2. Why is it that the pains travel around the body? Example. One day it's the neck, another day it's the arm, and then it's the knee? Then one day you can sleep and another day you can't sleep and then sometimes you wake up with pain and then maybe if you are lucky one day for 3 hrs. there is no pain and it comes back like you've been punched?
