Does muscle strain cause lower back pain?

Muscle-related pain is often linked to a particular activity and may ease when the back is supported or the position changes. Tightness can limit bending, while coughing or bracing may briefly increase discomfort. Pain can also arise from joints, discs, nerves, or other conditions, so symptoms travelling into a leg, altered sensation, or weakness should be mentioned during assessment.

Continue light daily movement as tolerated, such as short walks, and change position regularly. Avoid heavy lifting and repeated twisting while pain is active. A wrapped cold pack may be useful soon after a flare; gentle heat can feel soothing for stiffness. Resume strengthening in stages when ordinary movement is easier, with advice from a clinician or physiotherapist if recovery is slow.

Seek urgent help for new bladder or bowel-control problems, numbness around the inner thighs, severe leg weakness, or back pain after major trauma. Prompt review is also needed for fever, unexplained weight loss, or pain that is severe and unrelenting. Arrange an appointment if symptoms interfere with daily tasks or do not begin to improve.

What findings suggest a muscle strain rather than nerve irritation? Which activities can I continue, and when should I begin strengthening? What changes should prompt an earlier review?
