What are the Main Causes of Lower Back Pain

There are many types of problems that can be the cause of lower back pain symptoms. Most are not serious and usually the symptoms get better with time and non-surgical treatment. Several trustworthy groups (2,3,4) have developed guidelines that help us decide what is the cause of lower back pain, they recommend that lower back pain is grouped into three main categories:

  • Non-specific low back pain (simple low back pain)
  • Nerve root irritation
  • Specific ( or more serious) problems.

Each of these groups of back pain has different sub categories within it. The following infographic gives an quick overview.
