👉 Tabering is a medical condition that occurs when the body's blood vessels constrict, which can cause the heart to pump less blood through its walls. This can lead to reduced oxygen and nutrients delivery to the muscles and other tissues in your body. It can also cause pain or discomfort in the chest, back, neck, arms, legs, and feet. Tabering is a common complication of certain medical procedures such as heart surgery, stroke, and lung disease.
