In the US, lower back pain is one of the most common conditions and one of the leading causes of physician visits. At least 4 out of 5 adults will experience it at some point in their lives. The pain intensity is often unrelated to the severity of the actual injury. For example, lower back spasms from a simple back strain can cause excruciating lower back pain that can make it difficult to walk or even stand, whereas a large herniated disc or completely degenerated disc can actually be completely painless.

Symptoms of Chronic Back Pain
People who struggle with back pain may experience the following:

    Shooting or burning feeling
    Tingling or numbness
    Hard to move, which stops you from walking or standing
    Pain that moves around to the groin, buttock or upper thigh
    Pain that is achy and dull
    Severe muscle spasms, which can be severe
    Soreness of back and legs

Pain Severity
Doctors say that the severity of back pain is:

    Acute — If pain episode is less than 3 months
    Chronic — If your back bothers you most of the time for longer than 3 months
    Recurrent — If acute symptoms come back. Most people tend to have one or more episodes of recurrent back pain
