I have severe pain in my right rib cage. All the mechanical tests (X-ray, ultrasound, MRI) came back normal for organs, lungs, gall bladder, spleen. However blood work reveals both red (10K) and white blood count (16K) are low. I have been in pain since May and have lost almost 30lbs without dieting or exercising and I am so tired. Is this just mild anemia like my octor says?
