are you ok now? Im not a doctor, but I would call 911, if you are in pain and worried it may be your heart...

I have been having that too. It's kinda freak' me out. Going to tell my Dr. Let you know.

Unfortunately I think this is just another fibro thing but definitely ask your doctor about it!!

I have had ct scans mris x-rays dr says they all dont show anything...it feels like a stabbing/shocking pain sometimes shoots across my back where my bra strap goes hurts to where a bra....

I have the same at times. I believe the reason I can feel my heart beat all over my body is due to hypersensitivity in the limbic system of the brain. Look up Dynamic Neural Retraining system by Annie Hopper.
