Pulled muscle: what to do

A strain is an injury to muscle fibres caused by sudden force, repeated loading, or a stretch beyond the muscle’s current capacity. Pain may be sharp at first and later feel sore or tight. Tenderness, reduced strength, cramping, and bruising are possible. The affected area depends on the activity: it may be the calf, thigh, back, neck, or another muscle group. The [Muscle Strain](/conditions/muscle-strain/) guide explains the condition, while [Muscle Soreness After Exercise](/symptoms/muscle-soreness-after-exercise/) describes a different pattern that often follows exercise without a single sharp incident.

Stop the movement that caused the pain and avoid testing the muscle repeatedly. Rest from heavy loading, but keep nearby joints moving gently if that does not worsen symptoms. A cloth-wrapped cold pack may ease discomfort early on. Do not apply ice directly to skin. When ordinary movement is comfortable, add easy range-of-motion work, then light resistance. Increase one demand at a time and pause if pain becomes sharper or strength drops. Pain relief medicines may not suit everyone, so check with a pharmacist or clinician if you have other conditions or take regular medicines.

Seek prompt assessment if you cannot use the limb normally, notice a visible gap or major loss of strength, or have substantial swelling or bruising. Urgent care is appropriate after a serious accident, with new numbness, or when the limb becomes unusually cold or pale. Arrange an appointment when symptoms keep limiting daily tasks or fail to improve with protected activity.

Ask how severe the strain appears, what activity is safe now, whether you need physiotherapy, and what signs mean you should stop rehabilitation. Tell the clinician when the pain began and whether there was a pop, fall, or sudden change in strength.
