What Causes Upper Left Back Pain and When to see Doctor
Upper left back pain can be alarming, especially when you are not sure what is causing it. Upper back pain is less common than lower back pain or neck pain. A major concern about upper left back pain stems from is proximity to important structures in the upper back.
Pain in the upper back, particularly on the left side, may feel like a dull ache or a stabbing pain that may be quite intense. Although the pain may settle soon, it may be a cause of concern because of the area of pain involved. The intensity and the nature of upper back pain vary from person to person, depending on what is causing it.
What Causes Back Pain on the Upper Left Side?
To know what upper left back pain is, it is important to understand how the upper back moves and functions. Imagine the bones of your spine stacked one on top of the other. Each vertebra is cushioned in between by a disc, which absorbs shock from movement. The higher few segments allow your neck, shoulders, and arms to move. The lower few segments allow your lower back, hips, and your legs to move.
The upper back is a segment in the middle that moves relatively less. Now this area is more stable than the other segments and is also attached to the ribs. The muscles around the upper work along with the vertebrae when this area moves to perform any activity. So there is a much lower chance of injury to the spine itself, while pain due to strain to the muscles is more common. The pain may
What Symptoms Can You Experience During Upper Left Back Pain?
Upper back pain may occur on either side of your back. One-sided pain occurs frequently among patients. Upper left back pain presents with one or more of the following symptoms:
You may feel generally around the upper back, under the shoulder blade, even till your arm. The pain may range from mild discomfort to excruciating levels. Sometimes the pain occurs on both sides of the upper back.
You may notice general stiffness around your upper back after prolonged rest. This stiffness may also be noticeable after continuous activities or postures.

Upper left back pain may be accompanied by a general sense of discomfort. As pain may be felt around the upper back in the neck, shoulder, mid-back, and arm, you may feel uneasy. The area may also feel tender to any touch.
Many times upper back pain may exhibit along with postural changes in the upper back. This is often seen among females with upper back pain post-menopause following osteoporosis.
Upper left back pain may also occur along with tingling or current like sensation reaching till the fingers. This happens when there is irritation of the nerve root in the upper back.
If the upper back pain originates from increased pressure of nerves, it may present with numbness. Numbness occurs in the area that is supplied by the compressed nerve and may occur anywhere between the upper back and the fingers.
Often increased pressure over a nerve may cause fatigue able weakness. You may find yourself unable to perform routine tasks or the muscles of the upper back or arm may tire easily.
What are the reasons for Upper Left Back Pain?
Muscle injury from overuse
Muscles around the upper back may get strained on continuous or repetitive work and get injured. Activities like twisting, lifting heavy loads, and bending may put added stress over these structures.
Pain from continuous postures is common among those who have to maintain the same posture for long hours. The muscle is unequally loaded and undergoes tremendous strain, often causing semi-permanent or permanent changes to posture.
Pain in either or both sides of the upper back may originate due to slipped disc, or disc herniation. The pressure over the intervertebral disc increases, damaging the disc and giving rise to pain.
Traumatic injury due to an accident, fall, or sports activity may strain any of the structures in the upper back. This may lead to upper back pain.
Osteoporotic compression fractures
Osteoporosis causes loss of mineralization in bones. This makes bones fragile, and one of the most common sites for osteoporotic fractures in the thoracic vertebrae in the upper or mid-back. The fracture is caused by compression of the vertebral body and may give one-sided pain if it affects the nerve root exiting near it.
Diseases not related to the spine and other skeletal structures
Upper left back pain may also occur due to causes not related to musculoskeletal structures. These are the conditions causing pain in the left upper back area:
Heart attack or myocardial infarction may cause pain in the left upper back, chest, left arm, shoulder, and jaw. The pain location though usually on the left side, may even occur on the right side. It may be accompanied by a feeling of tightness, breathing difficulty, or weakness.
Tumors in and around the spine area in the upper back may lead to pain in the upper back. However, pain due to a tumor will often show signs related to the growth of the tumor.
Other visceral organs
Pain arising from other visceral organs such as the lungs, kidneys, or pancreas may be felt in the upper back. This may be due to infection, tumor, or abnormalities in any of these organs.
