I am sorry to read about everyone's problems here, but I have to say, it's been helpful to know I'm not the only one.
I've been dealing with my issues, though, for 3
years now. I've had all of the tests mentioned here, some more than once,

and because of my history of cancer they've thrown in even more fun tests like MRIs, and bone and CAT scans for good measure - all of which have been negative so far, thankfully. We still don't know what's causing my pain.

We were hoping it was gallbladder so we could take it out, but even the HIDA scan was negative.
One thing I haven't seen mentioned here at all which I stumbled across myself recently, is that sometimes statin drugs can cause a lot of GI complaints. If you're on a statin and having GI issues, it might be worthwhile doing some research into them and considering whether to try something different for lipid management. I came off lipitor on Memorial Day weekend, and my pain has improved quite a bit.
I also wanted to mention that when my mother was younger, she had ulcers, at one time they bled. Back then (in the 70's), the best they knew how to treat them was to recommend a diet of cream - yup, cream. No PPIs back then. These days, we've come a very long way with diagnosis and treatment.
BTW, my GI doc recommended I take my prilosec 1/2 hr before I eat in the morning, and if I need a second dose, to take it around 4pm, or 1/2 hr before supper (ideally, on an empty stomach). Sometimes I take maalox tabs, too (chew and drink 1/2 glass water). I'm a pro at this now!
I hope Silly Me and everyone else finds resolution to their problems!
