since you message is two hours old now (webmd answers is not an emergency response service! ) i suspect the bleeding has stopped by now. in most cases these avulsion-type cuts will bleed quite freely but steady pressure/compression on the wound (without peeking! ) for at least ten minutes or so should suffice. compression and time will allow these tiny severed blood vessels to close. once the bleeding has stopped you can inspect your wound to see if suturing is requiried. if so you have have an 8 hour or so "window" to have this done. if the flap of skin has been completely severed and the wound is small it should heal and new skin will cover the area. if the flap is hanging on and is pink (means it has a viable blood supply) allow this piece to cover the wound and it may re-graft. obviously without seeing it it is difficult to offer you patient-specific advice.
i have a gouge on the mid-tip of my thumb;a piece the flesh is gone; it keeps bleeding no pain. how do i treat it? . thumb was caught in the metal prongs of a wine opener and pulled the skin off. it does not look like a stich is possible as the laceration is more like a hole. when i remove the bandage it still bleeds and i am unable to put any ointment on the wound. it was done at 35 000 feet in the air; i work as a flight attendant.
