Nosebleed
Nosebleeds are common and rarely indicate a serious medical problem. However, frequent nosebleeds, a bleed that lasts longer than 20 minutes or occurs after an injury may require medical attention. Dry air is the most common cause of nosebleeds. Antihistamines and decongestants can also dry out the nasal membranes and cause nosebleeds. Frequent nose blowing is another cause. Nose bleeds can also result from medical conditions, such as blood disorders.
