Female lumbar muscle strain does not usually cause frozen shoulder pain. 1. Lumbar muscle strain, also known as functional lumbar pain, is mainly due to sedentary or lumbar long-term position, resulting in lumbar muscle congestion, edema, fatigue injury. Mainly manifested as soreness, swelling and pain along the spine on both sides of the muscle path, aggravated by exertion or cold, generally can be relieved after rest. The pain is often limited to the lower back and does not lead to symptoms of frozen shoulder. 2. Frozen shoulder is based on chronic aseptic inflammation of the shoulder joint capsule and its surrounding ligaments, tendons and bursa, which mainly causes pain in the shoulder joint and limited activities, and a few patients can radiate to the neck or elbow, and patients who do not exercise properly or in time may also have different degrees of deltoid atrophy. Commonly known as fifty shoulders, mainly seen in female patients around fifty years old. If the pain symptoms of lumbar muscle strain are serious, or if the symptoms persist without improvement, the patient should go to the hospital in time for treatment.
