Symptoms of a blood clot in the hip include leg swelling, pain or tenderness in the upper leg, a warm sensation in the swollen or painful area, and discolored skin, states the Antiphospholipid Antibody Syndrome Foundation of America Inc. Only about half of people with deep-vein blood clots have symptoms.
Symptoms generally occur in one leg and may occur only when standing or walking. Diagnosis of a blood clot is crucial, as untreated blood clots can lead to a life-threatening condition, according to the APS Foundation of America.
A blood clot that forms in a vein deep in the body is known as a deep vein thrombosis, the APS Foundation states. Most of these clots occur in the leg or hip veins, although they can form in other parts of the body. Deep vein clots have the potential to break off and travel through the bloodstream to the lung, resulting in a possibly fatal pulmonary embolism. Anyone showing possible signs of a blood clot should seek emergency medical care.
