A blocked femoral artery reduces the blood flow to the areas of the thigh and calf, causing the pain that leads to claudication. [8] Severe pain caused by claudication can lead to a person having very restricted ability to move, and pain while resting is often a sign that the condition has worsened.
The ankle and foot naturally pronate and supinate by about 5 degrees while walking or running. The red arrows indicate excessive pronation. In general, overuse injuries are the result of repetitive impact between the foot and the ground. With improper running form, the force of the impact can be distributed abnormally throughout the feet and legs.
The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
At initial symptom onset pain typically occurs following activity, but as the condition progresses pain is frequently felt during activities and may be present at rest. [6] Pain may also be present above and below the knee, where the ITB attaches to the tibia. [7] Pain is frequently worsened by running up or downhill or by stride lengthening. [8]
Rest pain is a continuous burning pain of the lower leg or feet. It begins, or is aggravated, after reclining or elevating the limb and is relieved by sitting or standing. It is more severe than intermittent claudication, which is also a pain in the legs from arterial insufficiency. [citation needed]

Symptoms may also include intermittent claudication or pain at rest. In late stages, paresthesia is replaced by anesthesia (numbness) due to death of nerve cells. [11] In severe cases, gangrene can occur suddenly and spread rapidly, [12] and should be treated within six hours of ischaemia. [13]
