I am experiencing pain to my left side under the rib cage and across the top of my abdomin. Along with that, sometimes pain around my back. I have been back to my Dr. Numerous times. She orders blood work, ( to ck.enzymes). Tests I have had in the last 3 yrs. are: ct scan, MRI, X-rays, endoscopy and most recently an ultrasound of gall bladder, liver,pancreas,and kidneys... In which all blood work and test were normal. I eat healthy, walk, and I m at my perfect weight. When I get these episodes they last a week or so and I experience fatigue, loss of appetite, some nausea. I just don t feel like going anywhere or doing anything. I am 66 yrs. old ,retired and take high cholesterol meds and a vitamin D pill daily. After all test come back normal, I am being treated for acid reflux (omephrazole) and later she had me try dexitant., and told that it could be caused from stress. I m constantly belching and have gas and bloating. I stay away from caffeine and spicy foods. I am sick of taking tests, which turns out normal,but can t seem to figure out why I still have pain..... HELP..Donna I m thinking of taking Nexium 24 OTC on my own!
