Ischaemic legision, commonly referred to as ischaemic leg pain or ischaemia, occurs when there is reduced blood flow to the legs, often due to narrowed or blocked arteries. This condition can lead to symptoms such as pain, cramping, or weakness in the legs, especially during physical activities like walking. If left untreated, it can result in more severe complications, including tissue damage or gangrene. Managing ischaemia typically involves lifestyle changes, medications, and sometimes surgical interventions.
