Does leukemia bone pain come and go ? and does it usually affect bones in pairs (for example, 2 legs, 2 arms, etc )?

Bone pain is not a reliable indicator of leukemia. Diagnosis requires examination of blood and bone marrow. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
