The condition called claudication arises from poor circulation--especially during exercise. Claudication most often affects the blood vessels in your legs but also can spread to your arms. The disorder stems from peripheral artery disease in which the arteries that supply blood to your arms and legs are damaged. Symptoms include pain when exercising, especially in your feet, calves, thighs and hips. You also may experience an aching or burning feeling and pain in your legs even when resting. Depending on the severity of the case, medication or surgery may be options for treatment, according to the Mayo Clinic. Always consult a physician if you suspect you have a medical condition.
Sciatica is characterized by pain or numbness in the back of the leg. According to the National Institutes of Health, most sufferers find pain relief through non-surgical treatments such as physical therapy or prescription drugs. The sciatic nerve runs from your spinal cord to your buttock and down the back of each leg. Sciatica may develop as the result of a herniated disk in your lower back, tumors or a pelvic fracture. Symptoms may include pain in your thigh or calf, lower back or buttock as well as muscle weakness and a tingling feeling in your toes or feet.
Peripheral neuropathy is a condition that is caused by nerve damage. Diabetics most commonly suffer from this problem. According to the Mayo Clinic, other issues that cause this disorder are extreme injuries, infections and exposure to toxins. Symptoms include burning pain, extreme sensitivity and numbness or tingling in the hands or feet. Such symptoms are treatable with medication.
