Poor circulation often leaves noticeable marks on the body. Icy cold hands and feet, tingling, numbness, or wounds that take longer than usual to heal are classic early signs. Sometimes one leg, foot, hand, or even a single toe feels different from the other—colder, paler, weaker, or simply unusual. These symptoms are easy to dismiss, yet they indicate that blood may not be reaching your extremities properly. Persistent changes in skin color, temperature, or healing speed should never be ignored. They are especially important warning signals for people with diabetes, high blood pressure, or a family history of heart disease.
