Definition: Pain felt in your lower back may come from the spine, muscles, nerves, or other structures in that region. It may also radiate from other areas like your mid or upper back, a hernia in the groin, or a problem in the testicles or ovaries. You may feel a variety of symptoms if you’ve hurt your back. You may have a tingling or burning sensation, a dull aching, or sharp pain. You also may experience weakness in your legs or feet.
