I was once taken to A&E with extremely bad pains that went to my sides and back as well. My blood tests came back fine and I had a full body scan and a ultrasound and everything was perfectly fine. I found out that the stress had caused my symptoms to worsen and I was creating an image in my mind I was dying or needed an operation.
I was fully recovered the next day, still not sure what was wrong with me but doctors and surgeons found nothing
