Despite rest and aspirin therapy it has not improved. He has not had similar back pain in the past and has been in good health. There are no neurological signs or symptoms on examination and he has no other complaints except possibly increased fatigability, which he attributed to his age. The remainder of his examination is normal with the exception of some conjunctival pallor.CBC: Hematocrit/hemoglobin - 31%/10.1 gm/dLMCV - 90 fL MCH - 32 pg MCHC - 31 g/dLWBC - 8,500/μLDifferential - normalPlatelet count - 230,000/μLSMEAR MORPHOLOGYNormochromic, normocytic red blood cells with prominent rouleaux formation (stacking) and a vague bluish background on the slide.QuestionsWhat feature(s) of this case might distinguish it from a routine lower back pain evaluation?What further evaluation is indicated?
