Internal bleeding is when you lose blood inside your body. You’ll most likely be taken to the ER. You’ll get fluids injected to keep your blood pressure from falling dangerously low. An ultrasound, a CT scan, or both can show if you’re bleeding inside. Depending on your condition, your doctors may decide to take you to surgery, or watch and wait. Sometimes, internal bleeding from trauma stops on its own. If you’re seriously injured, doctors may operate on your within minutes after you get to the hospital.
