How do I know if this new problem is fibro-related?

Fibromyalgia has so many symptoms that it's all too easy to blame every new thing we find wrong on it. Don't. It's all too easy to overlook signs of other, treatable diseases until they become severe enough to create real problems. Check with others who have fibro – join a support group or find a good online discussion. If most people don't experience that symptom they way you do, see a doctor. Even fibromites get other illnesses.
