Help

Praying for answers. Anything to lead to some help. Have had same symptoms for a year. It hasnt killed me but feels like it could if the pain got worse. Have had endo, blood tests and cardio tests to rule out everything that comes to mind plus a MRI of torso. I eat healthy. Drink socially but rarely and one to two drink maximum when I do.
Low magnesium on some blood tests, High d-dimmer on one attack that I went to ER for, always have high Sed rates.
Pain in chest radiates from sternum and throughout torso. Pain is dibilatating and excruciating. Have the ability to move but cant from such intense pain with bad attack. Can apply pressure only if not a full blown attack but NO pressure can be applied during an attack. It feels like it will kill me if I dont find the source of the problem.

Have severe IBS but I eat healthy to keep IBS from bothering me. Cannot digest milk products or corn products. It does not seem to be a precurser or irratant to chest pain. Chest pain started two months after removal of gall bladder.
I took sucralfate, anti spasmotic med and prilosec plus zantac for six months to no avail. Nothing helped.

Attacks happen when I am calm, happy and comfortable. I live a low stress life and enjoy it.
