The chronic whole body pain does not necessarily mean leukemia. Your CBC report is within limits as attached herewith (attachment removed to protect patient identity). For your condition, your physical examination first should be done in the form of liver, spleen and lymph nodes palpation. Check your calcium level as well. Your vitamin D level is slightly low below reference range and for that Cholecalciferol sachet with milk 50000 IU per ml can be prescribed once a week for six weeks.
Check your liver and kidney profiles report as well. High ESR could be from inflammation or infection as well. Check your thyroid status as well by serum TSH (thyroid stimulating hormone) estimation. CT scan like higher investigation can be planned if needed. Serum protein immunofixation electrophoresis will be beneficial to rule out multiple myeloma if needed. Take care.
