Hemothorax
Symptoms of Hemothorax
Hemothorax is not painful, but the injury that caused it usually is. The severity of other symptoms depends in part on the amount of blood in the chest cavity. If the amount of blood is small, people usually have no other symptoms. People with a large amount of blood may feel short of breath, and breathing may be shallow and rapid. A massive amount of blood may cause blood pressure to become dangerously low ( Shock ). The skin may be cool, sweaty, and bluish.
