I am sorry that I hadn't responded to this sooner. Although I am not a doctor and can not diagnose you, I would urge you to check your symptoms against a checklist like this one:

Then, I would suggest seeing your internist and getting a referral to a specialist, preferably a rheumatologist as fibro is an arthritis-like disease and that's what rheumatologists specialize in.
To get a diagnosis of this condition, you'll have the "tender points" test. Here's a chart and a brief explanation of where the tender points are & how one gets diagnosed with FMS:
