text: I would say maybe you hit a spot on your spine which is causing the numbness. Stress could be making your chest numb but I think it's more than that. Even though you/ve had an mri and x-rays done...sometimes they can't show the real culprit. I would advise to get some more opinions of other doctors, check medical websites...but definitely don't let this go. It could be serious nerve damage. If you hit certain spots on your spine, nerves that carry impulses to the brain malfunction and can't carry signals as well anymore giving you the feeling of numbness or tingling and can spread down your legs or arms. Good luck....keep searching for answers.
