When my IBS is acting up I also get a pain in the chest bone area and some dizziness. Of course my neck hurts, and elbow bones on both sides with great fatigue , yet not being able to sleep. Does this sound like fibro.? I have had all the heart tests and they were all normal for my age-57-. Also, one big pain area for me is my sciatica, some days to the point I cannot get out of bed for a long while, then I am in pain for days with a dull pain left there for months.
