Do people with blood loss have a lot of pain?

Blood loss symptoms. People with blood loss do not have pain just on account of the blood loss. Blood loss can be rapid and acute or slow and chronic. The effects of blood loss are to lower your blood pressure, increase your heart rate, and make you feel dizzy. It does not cause pain. But the same event that caused the blood loss (like a gun shot or trauma) may cause damage to other tissues which causes pain.
