I am a 29 year old female and have been suffering from chest pain. I have had multiple Ecgs, blood tests, 2 chest X-rays, exercise stress test, ct scan, ultrasounds of upper stomach region as well as a pelvis ultrasound, I have had a brain MRI also for headaches, all tests have come back clear. I am taking Rabeprazole for gerd although did the breath test which came back negative. The pain is mostly at the top of my chest and is a constant pain, I also get pain under my left breast/ rib cage area and occasionally in the center of my chest. I m nearly at my witts end as no one can figure out what is causing the pain. Any ideas would be greatly appreciated?
