ibromyalgia
"I was sick with sinus infection and was taking Mucinex. I thought to myself, I am going to be extra sore since I am home from work and resting more than usual because I was not feeling well. I was shocked when after taking Mucinex for a few days, my pain was gone. No more tender spots. My arms had been really bad lately and when I touched them, they were no longer sore. I had no idea of the connection at the time. I googled Mucinex and was amazed that I found studies that something for a cold could possibly help with fibromyalgia. I stopped taking it and the symptoms came back so I started taking it again. I take 2-3 400mg a day. I call this experience accidentally on purpose. It may not work for everyone as we're all different but its worth trying."
