I Have Been Diagnosed With Fibromyalgia And I Am Questioning

I have been diagnosed with fibromyalgia and I am questioning if I have been mis diagnosed. I take glevec for CML which caused cramps and myalgia. I also suffer ocular migraines and widespread pain. It used to flare up and go away. I fell in 2011 and have not been out of pain for a single day since then so I don't know if I would call this a flare up or symptom of something else.
