Many people suffer from back pain due to a muscle strain. This is mainly triggered by doing everyday activities incorrectly. For instance, leaning over to pick up something heavy without bending at the knees.
However a simple coughing or sneezing fit can also pull a muscle or through exercise.
Pain that has developed through exercise is generally caused by over-using a muscle, such as doing too many reps, using weights that are too heavy for you or even by not warming up properly.
Another muscle strain could come about by wearing unsuitable shoes for running which can put a strain on your hip and back muscles.
Symptoms of pulled back muscles include back pain and muscle weakness and sometimes back muscle spasms. The back pain may be sudden, but usually comes on gradually.
The muscles stiffen or spasm to reduce motion to prevent further injury. Muscle injuries cause inflammation – a part of the healing process. Inflammation may trigger muscle spasms. Muscle spasms are more likely to be a problem for the first couple of days after an injury – when inflammation is at its worst. Though not serious, back muscle spasms can cause significant pain. Inflammation also causes pain.
