You had no risk for HIV because you used a condom. People get sick with sore throats and fevers all the time especially now during cold and flu season. There's absolutely no reason to assume this had anything to do with HIV. Condoms are used to prevent HIV. You used a condom and it didn't break. Therefore you had no risk.
I am sorry you are so anxious. In this situation it is unwarranted. As Chima said, protected sex is not a risk for HIV. You do not need any further testing. No risk means every test you ever take will be negative. So, you should move on. The ONLY ways people really get HIV is from unprotected vaginal or anal sex or sharing IV drug needles.
Same thing happened with me.1year ago my CBC show higher WBC , neutrophil 75% and lymphocytes 14%.I was sure that my HIV test will come back positive.I had chronic hiv symptoms but TESTED NEGATIVE.HIV specialist told,my CBC shows a non specific infection but it doesn't necessarily mean HIV and that time after 5 months of sexual exposure HIV rapid test was negative .So doctor told it's not HIV.
