If your legs hurt or feel heavy after a short walk, it’s not just about being tired. This could be a sign of poor blood circulation, or a more serious condition like Peripheral Artery Disease (PAD), where narrowed arteries reduce blood flow to the limbs. PAD can lead to serious complications if left untreated, including an increased risk of heart attack or stroke. Symptoms may include cramping, numbness, weakness, or coldness in the legs. Early diagnosis can prevent long-term damage. If you notice leg pain that comes and goes while walking or climbing stairs, don’t brush it off; visit a doctor for evaluation.
