Hello. I wanted to know what is the problem with my girlfriend's immunity. Sometimes she suddenly gets headache and fever followed by diarrhoea and vomiting. She had done tests and the report showed neutrophil in high amount. She took medicine and got fine. And then again after one or two months or in between a month, she again gets fever, headache, vomiting and then again goes back. What is the main cause. The fact that she got cavity before is it that her immunity is weak? And of course we had intercourse before but I did hiv test and it showed negative. So what could be the mechanism? And what would you prefer for weak immunity and high neutrophil?
