Pain under my Left Ribs that goes around to my back

I get pain under my left rib that goes around to my back. Many times it is worse when I eat but at times it worse if I move just right. It is tender to touch and feels bruised all the time. I was just diagnosed with CSID, is that part of it? I only have part of a stomach as I had weight surgery because I couldn't loose the weight I felt like crap all the time, no one would listen to me so I thought that was the answer but I really didn't loose the weight with the surgery either. It wasn't until I found a GI doctor out of U of M that ran the CSID test that found I have this rare disorder and I seem to have SIBO when they run that test. I have that test coming up next week and she believes I have it again for the second time. My CT can showed my spleen was normal size. I do have erosive gastritic of the stomach which means I can't take pain meds. I do have Fibromyalgia on top of all this to, so I have high pain tolerance They want me to see a Blood doctor for rare disorders. My issues is the pain under my rib cage, is it something I just have to learn to live with the rest of my life. Some times it takes my breath away. I'm tired of doctors and I dont want to live on meds the rest of my life, I'm only 49 years old and I have gotten off all meds but my migraine meds and acid reflux that I will have to be on the rest of my life. Any suggestion on the pain in my ribs?
