Hello, am a 31 year old female that was diagnosed with an abdominal aortic dissection as well as carotid and vertebral dissections a year ago. All are unrepaired but stable. My question, I am sick with a cough and fever for the first time since. I took tylenol, didn't help the fever, took lukewarm shower, that didn't work either. I am allergic to aspirin and was told not to take IBprofen anymore. Is it ok to take it once to get my fever to come down more? I'm worried!
