For the last couple of years I have noticed this now and it comes and goes but i'll get periods where when I eat I would get upper right back pain just below the shoulder blade that feels like a sharp shooting pain, it stays for about an hour after eating and it seems to get triggered every so often which is what is happening at the moment. I have had numerous tests in the past as I suffer with stomach issues and these included last year a gastrosocopy/colonoscopy, abdominal ultrasound, full range of blood work and a chest and spine x-ray which were done this year. I noticed this a couple of years ago the back pain after eating and I originally thought it was an acid reflux related alignment but it doesn't seem to be as PPI, acid blockers, antacids etc don't work for me and seem to make it worse overall. What exactly do you think this could be I read up online about it possibly being lymphoma or a gallbladder dysfunction? I'm currently in the process of travelling overseas for a couple of weeks for a holiday do you think I could wait until I get back based on the tests i've had in the past and this has been on and off for a while now?
