if the nosebleeds are coming from the same nostril the scab that forms on the slippery mucus surface of the inside of the nose may not be "holding". these areas can re-bleed quite easily so instead of having three nose bleeds you are really having one nosebleed. recurring three times. keep the nose moist (vaseline saline gel) and avoid picking out those boogers which may actually be a scab formation. if the nose continues to bleed after this you may need to have it chemically cauterized by your medical provider using a silver nitrate stick. make sure you read about the proper way of stopping a nosebleed since many people are doing it incorrectly. look up "nosebleed" or "epistaxis" in your webmd search engine and you will find some excellent articles and further suggestions.
