I had bloody vomiting w/mucous, headache, diarrhea, queasy stomach, achy ribs upon inspiration and nausea after initially throwing up a pizza from the night before. I am a 59 year old female with an old positive PPD from the 80 s. Other things that have occurred ... I had an untreated, repeatedly misdiagnosed UTI. I won t be getting a flu shot until this coming Saturday. What could be going on?
