Go to your chiropractor and have him/her tell you what is wrong. I had upper back pain and found out it was a muscle problem. I just turned 61 and there are things you can do so the aging thing isn't the cause totally. There is a really good exercise show on our PBS and the lady says that as you age, your joints need lubracation.Your chiro should give you stretching exercises, and if you google online you can get physical therapy exercises. You may just find out that you have a vertabrae out or something simple.
