I recently got an MRI done of both shoulders due to pain. The findings included "Diffuse hematopoietic marrow seen throughout the majority of the scanning range, appearance seen bilaterally". My primary care physician ordered a blood panel which came back normal. If bloodwork is normal, is there further testing I should have done to determine the cause? I am extremely fatigued to the point of struggling to get through basic household chores. My doctor hasn't requested anything further. Thank you for your insight.
