Poor circulation can have far reaching consequences beyond numbness. If tissues are chronically deprived of adequate oxygen and nutrients, cellular function is impaired, leading to delayed wound healing, increased susceptibility to infections. For instance, peripheral arterial disease (PAD), is strongly associated with intermittent claudication, non-healing ulcers, and in extreme situations, limb amputation.
Poor circulation also puts stress on the whole body. The heart has to work harder to compensate, which can raise blood pressure, and may even increase the risks of heart attack. At the same time, reduced blood flow over time can affect the kidneys and brain. Thus, recognizing early manifestations can prevent long-term morbidity.
