ibromyalgia
"When I first had pain 19 years ago, I was treated with Flexeril for six months.  I thought I was getting better.  I stopped taking Flexeril and it was a false feeling of wellness.  Two months later I was diagnosed with Fibromyalgia.  Now I am on Flexeril again after a car accident and it is helping. I only plan to stay on it a few weeks since I fear addiction."
