What causes left side back pain?
If you have left side back pain you may have non-specific lower back pain. This is the most common type of back pain. Without an assessment it is impossible to be sure of the exact cause of anyone’s pain, therefore I recommend that you go along to a doctor or physiotherapist and have an assessment. This will do two things, it will rule out any of the more serious causes of back pain and put your mind at rest, and you will also get specific advice for your problem.
