Muscular pain often presents as cramps, dull aches, or sharp soreness. The pain worsens with activity but improves with rest.  Vascular pain manifests as throbbing, tightness in the legs, changes in skin color, and cold sensations. The pain worsens when walking or standing for long periods and improves when you elevate your legs. This type of pain can be a sign of conditions like Peripheral Artery Disease (PAD).
