Symptoms

There are several symptoms associated with PAD. Among these are:

• Claudication: defined as painful cramping in hip, thigh, or calf muscles after routine exercise which subsides after resting
• Numbness in legs
• Weakness in legs 
• Coldness in lower leg/foot compared to opposite side 
• Discoloration in legs/feet
• Decreased nail growth on feet
• Hair loss or slower growth on legs/feet
• Slowly healing wounds/sores on legs
• Weak/no pulses in legs/feet
• Erectile Dysfunction in men
• With advance PAD, severe pain while at rest - temporarily alleviated by walking or hanging the legs 

However, it can also be the case that someone can have PAD and not know it because he or she does not display any outward symptoms. In fact, for every one person with PAD who shows symptoms, there are around four others who have PAD but don't show symptoms. THis makes PAD a frequently under-diagnosed disease.
