I've had a small bit of blood in my nose mucus for a few weeks now. i had a nosebleed 3 days ago but still have bloody mucus. what could this be?

Low Humidity: In the winter, humidity indoors is lower because of use of heating without adequate humidity. This dryness in the air can dry out the membranes in the nose causing bleeding. Use a room humidifier, a whole house humidifier or a simmering kettle on the stove. You can also try irrigating your nose with saline twice daily. Thanks for trusting HealthTap!
