Understanding the causes of lower back pain is the first step in finding a solution to relieve the pain. First, know that you’re not alone. Statistics show that up to 80 percent of Americans will have back or spine pain at some time in their lives. Much of the back pain we see at NeurosurgeryOne is in the lower back, in the area called the lumbar spine. The good news is that while there are many causes of lower back pain, it usually gets better on its own or with a few home remedies. Most patients will never have to visit a Denver spine surgeon.
