I may have ate a little too much...creamy soup about 2 oz., Smoothie Yogurt (4 oz.) and then I had some mushy zucchini..not all at the same time but probably within 30 minutes and all of a sudden the back of my neck and my upper back started hurting really bad...but I didn't feel stuck or anything. Does being stuck or eating too much come in different forms? I don't know it was just really strange...I'm 11 days post op...

Yes it can hurt when you have eaten too much or too fast.

I find I get a sharp left side shoulder pain when I over eat. I'm guessing that over eating caused your pain.
