DR Ginny, Is this basically what you were told to do?
Tilt your head forward and pinch the soft part of your nose (the nostrils) together just below the bony center part of your nose. Applying pressure helps stop the blood flow and the nosebleed will usually stop with 10 minutes of steady pressure — don't keep checking to see if the bleeding has stopped.
If you get a nosebleed, don't blow your nose. Doing so can cause additional nosebleeds. Also, don't tilt your head back. This common practice will cause blood to run into your throat. This can make you cough or choke, and if you swallow a lot of blood, you might begin vomiting.
Once you've stopped the initial nosebleed, don't lift heavy objects or do other activities that cause you to strain, and try not to blow your nose for 24 hours.
