Pain, Cramping, or Fatigue
Early in the disease, you may feel pain, cramping, or fatigue in your lower body when you walk or exercise. The pain with walking usually occurs in your buttocks, thighs, and legs. This symptom is called intermittent claudication because it stops when you rest. As the disease worsens, you may find that pain occurs when you walk for shorter distances. Ultimately, as the disease progresses, you may feel pain, usually in your toes or feet, even when you are resting.
If you do not receive PAD treatment, your symptoms may worsen, including severe pain, coldness, and numbness in a limb. You may experience sores on your toes, heels, or lower legs and dry, scaly, or cracked skin on your feet. Additionally, the muscles in your legs may become weakened and gangrene may occur.
