The bad news: Aspirin can cause side effects like nausea, internal bleeding or liver or kidney trouble. Aspirin can cause ear ringing. It can combine with viruses and cause a deadly problem call Reyes Syndrome that can hurt your liver.

The ugly: Aspirin allergy can cause hives, asthma, and a systemic allergic reaction called anaphylaxis which can lead to breathing trouble or even anaphylactic shock and death.

Aspirin-sensitive people can develop the aspirin triad, which are nasal polyps, sinus problems, hives and asthma.
