Dear Knot,I have FM and IBS-D. I'm forty seven and I had that chest pain thing so bad a few months back that I drove to my doctor's office thinking I was having heart trouble.EKG and all were fine. I hate that chest pain, it lasts for days sometimes. What I do now is take a Xanax (tranquilizer) and it always goes away. Then I know its tension or FM or whatever.I think dizziness comes from the anxiety we have from all these symptoms!!feel better soon.love to all, mama-
