Depression and anxiety could be caused due to pain in the back, specifically the lower back which has a number of nerves. The pain occurred because of a condition called spondylolisthesis which meant one of the vertebra has shifted downwards. Before proceeding with advanced treatments the doctors might use general medications and therapy sessions. If the therapy doesn’t prove helpful for more than a month then an x-ray scan can be suggested. After the x-ray, there are chances that the patient is then offered an epidural injection and if it fails to work then doctors might suggest surgery.
