I was just released from the hospital, after a 4 day stay. Tests performed CTA, EKG, Tilt test, Chest x-ray, tons of bloodwork. Healthy heart but Tilt test stopped 8 minutes in due to bp dropping to 80/0. I have upper back pain between my shoulder blades.. pressure, numbness, tingling and pain. The doctor ordered an MRI of the thoracic area, unfortunately after trying twice I could not handle being inside the 60cm bore. I was released to follow up with my PCP for an open MRI. What is causing the back symptoms if I have a healthy heart? YYYY@YYYY
