As I mentioned on insights I also have the same problem on my left side -- from my bra line down to the waist. You could draw a line down the middle of me (front and back). This was my first symptom last winter and it has never gone away. I am also experiencing some bladder problems -- sense of bladder urgency. This also comes and goes and I have not had a bladder infection. I am not sure if I am having a flare or not -- no new symptoms but all of my new ones are bothering me more than they were prior to my infusion last Wednesday.
