Your pain during eating sounds just horrible! Eating is such a basic requirement for daily living, I can’t imagine how this must be impacting your day to day existence! Makes you dread mealtime! Is this pain during eating or after? How long does the discomfort last?
Does it matter what kind of foods you eat?

You’ve already had gall bladder surgery as well as treatment to fix your Hiatal hernia and also gastric sleeve surgery. There’ve been significant changes to your digestive system and I’m wondering if there’s a correlation.
Did this pain all being after these procedures?

I did find this previous discussion in Connect… https://connect.mayoclinic.org/discussion/left-shoulder-pain-15-mins-after-eating/
I’m hoping some of our members can chime in with what they’ve experienced and what helped them,

After doing a little online research it looks as though this isn’t a rare symptom but really does warrant a trip to your doctor. This extreme pain in your left shoulder, from everything I’m reading, points to pancreatitis. To a lesser degree, it can also be triggered by heart issues, GERD and a hiatal hernia.
