Why have I have back pain and sometimes my chest hurts?

Chest pain. Many of the muscles in the intercostal spaces (between ribs) attach both to the rib cage/sternum (front) as well as the spine (back). Inflammation/pain at either site (front or back) can therefore affect the opposing side.
See a doctor. I cannot really tell why you have these pains. You really should see a doctor and have a good examination and medical evaluation.
