I am a 42 y.o male with Fibromyalgia.I recently had a minor/major Fibro flare-up when lifting a mattress off?

I went to lift a queen size mattress off the floor and prop it up against the wall….this triggered some serious fibromyalgia symptoms in my front neck and back….pain,nervousness,dizziness,GERD, sleep disturbance….it really made my frontal & back neck muscles rope up or spasm ….it seems like its taking forever to disipate…it happened 02/05/09….Should I get involved with an exercise physiologist to recommend muscle strengthening exercises so that it doesnt happen again….I mean….I am miserable….is exercise/strengthening the cause or cure???? Please advise?
