I have an uncomfortable bloating feeling in my right upper abdomen (under rib cage) and a nagging ache/pain in my right middle back that sometimes has a numbness or tingling feeling. Mainly on my right side, but sometimes on both sides. I have had various test to reveal nothing. CT-scan, colonoscopy, ultrasound. I drink wine every evening. I would say I drink close to a bottle every night and on the weekends maybe a little more. I know that it isn't good for me and I am trying to cut down. I have shared my concerns with my doctor. My blood tests have come back normal. They said my liver enzymes are perfect. Is it possible that a damaged liver would not show up in routine blood work? The doctor told me that if my liver was so damaged that it hurt, that it would show up in blood work. Is this true? Is there any test you would recommend for me? I also have very loose, dark stools all the time.
