I have a friend who has presented with symptoms of diverticulitis, has been hospitalized with low grade fever, been on massive doses of antibiotics, was checked for c diff and several other infectious diseases, began to get better and 3 days home has a blood pressure of 80/44, low grade temp and an inflamed uterus. They are now saying that preliminary blood work shows she is positive for STD but is not sexually active. What would now cause her to get that false positive and is it possible that salmonella from 4 years ago may have entered her blood stream and causing these infections?
