The real cause of worry is that why he blacked out which needs to be thoroughly investigated. There are so many causes of sudden blackout
that unless more information about the patient is not available it is not easy to pin point the diagnosis with the available data.
Some of the common causes of black out are Alcohol abuse
, Cardiac Arrhythmia
(Means irregular heartbeats) Sudden pain or emotional shock
, Low blood sugar
,people on severe dieting,Prolonged unaccustomed standing causing blood pooling.
I think that even if the bleeding has stopped you must seek medical advise as soon as possible to ascertain the appropriate management of the wound and the sore neck as well as to ascertain the
exact cause of black out.
