dear
Although you have been diagnosed with
fibromyalgia,we have to also rule out the neural pain in back aswell.
It is good that all the blood reports are normal.
please be assured that the food habits has nothing to do with the pain.If I would have been ypur treating doctor I would like to examine and investigate for any
nerve compression in back due to postural effects may be.
So please concentrate more on a physical exercise,have a balance diet with more fibre,fruits,protein and fluids.
For a persisting pain this time please have a
x ray of back bone (LSSpine) done with a consultation.
Otherwise you are fit and fine,be happy
hope this helps
most welcome for further queries
