Vascular problems can present a wide range of symptoms depending on the core issue. These include intermmitent pain known as claudication (a cramping heavy sensation, often in the legs), numbness, pins and needles, increasing pain with activity and exercise, weakness in the muscles, discolouration of the skin (changing to blue or purple) and wounds that don't heal, among others. It's crucial to seek immediate medical help if there's any pain that increases rapidly, you feel chest pain and shortness of breath, or if you lose feeling in a part of your body.
