In part 1 of this article, we looked at the composition of the shoulder joint, and considered possible reasons for left upper back pain that involves the shoulders. We continue with the third of those reasons.
Left upper back pain that relates to a shoulder fracture is readily determined, often by the patient. It is a pain that needs little explanation.
If your left upper back pain is related to a frozen shoulder on the left side, it will likely be a dull, aching pain. The pain will get worse when you try to move the shoulder. In most cases, your left upper back pain will be more focused over the outer shoulder area. You will have difficulty moving the shoulder, and it will feel stiff. Even if someone else tries to move the shoulder for you, it will be difficult to move.
Rotator Cuff Tendonitis
This left upper back pain is due to an inflammation of the left shoulder tendons. They become irritated and swollen. If the tendonitis is in your left shoulder, your left upper back pain will hit when you try to move the arm. You will probably feel pain at night, when you lie on the shoulder. Your pain will be worse when brushing your hair or reaching for objects above your head.
Rotator cuff tears
A rotator cuff tear is not an uncommon problem, and can quickly cause both left upper back pain and pain in the shoulder itself. A rotator cuff tear can be caused by repetitive use injury, or by falling onto your outstretched hand. If the tear is partial, you will still be able to move your shoulder, but will have pain. If it is a complete tear, you may be unable to move your shoulder as fully as before. The pain is similar to that of rotator cuff tendonitis.
A shoulder separation is usually related to sports activity or a vehicle accident. It most frequently occurs after a fall or a sharp blow to the shoulder’s top. The left upper back pain in this case will be focused at the top of your left shoulder. Tenderness or related pain may be felt at the joint between the collarbone and shoulder.
Whatever you believe is causing your left upper back pain and shoulder pain, you should seek the advice of a qualified health care provider. The information here is for educational purposes only.
