Symptoms of lumbar major muscle injury are mainly recurrent lumbar pain, activity limitation and other symptoms. 1. Recurrent lumbar soreness: lumbar major muscle injury usually manifests as lumbar soreness or swelling, and the pain may also radiate to the back or buttocks. The pain may worsen after overexertion or exposure to cold. 2. Restricted activities: As lumbar nerve is compressed by lumbar major muscle injury, which leads to stiffness and pain in the lumbar muscles, the patient’s activities will often be restricted. 3.

When patients have recurrent lumbar pain for a long time, they should not be treated blindly and should go to the hospital in time for relevant examinations to clarify the cause of the disease and carry out relevant treatments as soon as possible to prevent the condition from aggravating.
