Thank you for the advice. I have done a heart ultrasound and everything seems to be fine. I plan to do an ECG as well. The tests I`ve done so far includes abdominal CT, chest x-ray, gastroscopy, blood and urine exam and all I was diagnosed with is erosive gastrotitis and a small esophagitis, neither of which gives me typical symptoms of GERD, plus after taking acid reduction medicine, nothing has changed about my rib cage/exhalation condition. I am at the end of my wits now.
