When should I consider lower back pain to be serious and seek medical attention?
Seek medical attention for lower back pain if it is severe, persists longer than a few weeks, or is accompanied by warning signs such as numbness, weakness, tingling, fever, unexplained weight loss, or loss of bladder or bowel control. These symptoms may indicate a serious underlying condition—like nerve compression, infection, or spinal injury—that requires prompt evaluation. Early diagnosis often leads to better outcomes and can prevent long-term complications.
