What can reverse the 'fibrositic nodules' in people with fibrositis or fibromyalgia?

For 3 yrs., I've been suffering from fibromyalgia on my left shoulder, pectoralis,and most especially on my intercostal muscles. As we have found out,this is all the result of a certain abusive habit since I was 11 yrs. old and now I'm already 22. It's really hard to explain it here. But I can say that this 'abusive habit' I'm talking about had been repeteadly strained my intercostals until the fibromyalgia had already manifested...3 yrs. ago. Now my condition have only mitigated a bit and I'm still suffering. So what I really need is for my palpable 'nodules of tightened muscles' to be reversed.
