When a blood clot occurs in an artery, it impedes or totally blocks blood flow to certain tissues, and pain is usually the first symptom, states MedicineNet. If a blood clot occurs in the coronary arteries, the individual may experience heart attack symptoms, such as chest, arm, neck or jaw pain, and shortness of breath, notes eMedicineHealth. A clot that forms in a brain artery can cause stroke symptoms, which may include speech difficulty, arm weakness and facial drooping.

If a blood clot lodges in the intestinal arteries, the individual is likely to experience extreme pain and bloody diarrhea, reports MedicineNet. A blood clot in the extremities results in paleness of the affected area, weakness, loss of feeling and possible paralysis.

Some blood clots do not produce any symptoms unless they rupture or travel to another part of the body, explains MedicineNet. When a blood clot breaks free and travels to the lung, it causes a potentially life-threatening condition called pulmonary embolism, according to eMedicineHealth. Chest pain and shortness of breath are the main symptoms.
