Hello everyone. I'm a 55 yo male in the USA. I feel like I'm in relatively good health, but I've been experiencing mild dull upper stomach pain, especially after I eat, that radiates or refers to my mid-back. My energy level is the same it's always been and I've lost no weight or appetite. I can bike 40 miles, run, lift weights. My blood tests are all within range. An ultrasound showed some gallstones, but they weren't deemed a problem. My upper endoscopy last Monday did not seem to reveal any ulcers, gastritis, etc.--which actually kind of worries me as I hope it'd be a simple stomach problem. On Wednesday I go for a CT scan of my abdomen and I'm really worried that cancer, especially pancreatic or liver, will be revealed. Help!
