Fingertip injury caused by knife

Patient: I cut my left hand index finger on sunday the cut is on the very right hand side of the nail and about a cm in depth.. i bandaged it and there was severe bleeding .. i then used paper stitches to pull the cut back in place but still it is showing as open but not bleeding or pussing. And sensitivity is still numb is there anything else i can do as im using paper stitches and a plaster atm many thanks adam
