Bleeding

One of the potential side effects from chemotherapy treatments is low blood platelets, which may result in a bleeding disorder (unexplained bruising and bleeding).

You should be watching for the following:
- tiny, red, pinpoint spots on your skin (petechiae)
- bleeding from a cut that doesn't stop after a few minutes
- bleeding from your mouth or nose (nose bleed called epistaxis)
- black or bloody stools
- bleeding from your vagina when you are not having your period (menstruation)
- bleeding during your period that is heavier or lasts longer than normal
- changes in how well you see
- feeling confused or very sleepy
- changes when you go to the bathroom
- blood in your urine (the urine will have a red or pink color to it)
- head or vision changes
- bad headaches

A runny nose occurs when the tissues or blood vessels in your nasal cavity produce excess mucous. This excess mucous is the result of the body trying to remove viruses, irritants, and allergens.

Runny nose can be caused by a cold, influenza, allergies (to dust, pollen, pet dander, etc.), or as a response to tobacco smoke or spicy foods.

A runny nose usually clears up on its own, but you should see a doctor for any of the following scenarios:
- if the runny nose does not improve in 3 to 4 days
- fever
- shortness of breath or trouble swallowing
- colored mucous (green, brown, black, etc.)
- bleeding, bruising, or rashes
