How common is lower back pain in muscle strain?

A strained muscle or tendon in the lower back can cause a sore, tight, or pulling sensation. Pain may increase when you bend, twist, cough, or use the affected muscles, and the area may feel tender to touch. Muscle spasm can make movement feel restricted. The timing of symptoms after a specific activity can help a clinician understand the problem, but lower back pain can also come from other tissues.

For the first few days, reduce the activity that triggered the pain while continuing easy movement as tolerated. Brief walks and frequent changes of position can prevent stiffness. A wrapped cold pack may ease discomfort soon after an injury; gentle heat may be more comfortable once tightness is the main issue. Resume lifting and exercise in stages, using good technique and stopping if pain becomes sharper or starts spreading.

Contact a clinician if the pain is not improving, keeps returning, or makes ordinary activities difficult. Get urgent help for bladder or bowel changes, numbness around the inner thighs or groin, new leg weakness, fever, unexplained illness, or back pain after major trauma.

Ask which muscle groups may be involved, whether you need a physiotherapy assessment, and when to restart work, sport, or heavier lifting. Ask what warning signs should prompt a faster review and whether your usual medicines are appropriate for this episode.
