Make sure: Talk to your doctor about other possibilities other than routine back pain. At your age, there are worse scenarios. Then, get off the couch! exercise, specifically core- strengthening, and low impact activity are shown to improve pain. Stop any tobacco use. Yoga may be the best therapy studied to treat back pain. Above all, beware using ibuprophen and other non-steroidal anti-inflammatories.

Spine Pain Options: This chronic pain in the distribution as you suggested is the result of an irritated nerve or facet joints or other injury typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease, etc requiring further evaluation by a spine specialist and may be candidate for facet injections/radiofrequency ablation and epidural steroid injection.
