The occurrence of lumbar muscle strain is mainly due to chronic injury causing excessive fatigue of the muscles, resulting in muscle fiber strain. Lumbar muscle strain is primarily a type of chronic aseptic inflammation, characterized by symptoms such as pain and restricted movement. When lumbar muscle strain occurs, it is not advisable to continue running; instead, it is recommended to apply heat and rest. This is because running can exacerbate the load on the lumbar region, which is not very beneficial for lumbar muscle strain. Therefore, when lumbar muscle strain occurs, rest and appropriate physical therapy should be the main focus.
