See A Dentist: Without more information as well as a clinical exam, it would be difficult to determine what is going on. Dark red swelling would suggest a collection of blood, i.e., possible hematoma or bruise, and sensation of a sharp cut suggests a history of trauma. You need to be seen by a dental professional for further evaluation and treatment as indicated.
