Internal Bleeding : There is little that you can do for most internal bleeding other than treating for shock and calling for a doctor immediately. If the patient's condition becomes worse without any external injury, one possible cause is internal bleeding.
Internal bleeding should always be suspected after a violent blow has been sustained and shock symptoms become apparent.
However, one common type of internal bleeding that you can treat is a nose bleed. For nose bleed,
(1) the casualty must be made to sit upright with his/her head slightly forward,
(2) his/her nose pinched just below the hard part for 10 minutes,
(3) tell the casualty to breathe through mouth,
(4) do not attempt to plug the nose, and
(5) seek the medical help immediately.
This procedure should be followed in all cases, though persistent bleeding from the nose should receive professional medical attention.
