Claudication refers to muscle pain due to lack of oxygen that's triggered by activity and relieved by rest. Symptoms include the following: 
Pain, ache, discomfort or fatigue in muscles every time those muscles are used
Pain in the calves, thighs, buttocks, hips or feet
Less often, pain in shoulders, biceps and forearms
Pain that gets better soon after resting
 The pain may become more severe over time. You may even start to have pain at rest. Signs or symptoms of peripheral artery disease, usually in more-advanced stages, include: 
Cool skin
Severe, constant pain that progresses to numbness
Skin discoloration
Wounds that don't heal
