For about 3yrs I have gotten severe back and neck pain after eating esp if the food is sugary There's no lower abdominal pain and it happens almost immediately lasting about 30mins What could it be?

Answer 1

If the foods have high fat or grease (example: ice cream, potato chips, french fries), it may be gallbladder pain. GB pain can feel like it is going through, from front to the back and can involve the shoulder/neck. Try to reduce fat intake at each meal and ask your doctor if an ultrasound of the gallbladder would help diagnose your problem.
