A medical emergency such as a pulmonary embolism or a heart attack might be the cause of your back discomfort while breathing if it is intense and abrupt. Lower back discomfort during breathing can be caused by a variety of factors, ranging from inflammation and chest infections to spinal curvature and lung cancer, among others.
When you take a deep breath, it is possible that your back pain could get worse. This is due to the fact that your rib cage is related to the vertebrae of your spine. Generally speaking, this is not a cause for concern. However, this sort of discomfort might occasionally indicate the presence of a pulmonary embolism (blood clot in the lung).
What are the symptoms of back pain and difficulty breathing?
Having back discomfort that is accompanied by trouble breathing indicates that you are suffering from a heart attack or arrhythmia, which is a life-threatening emergency that requires immediate medical attention. There are instances where a heart attack progresses gradually, despite the fact that it usually occurs quickly.
