As an STD assistant, I understand your concern about HIV symptoms. The most common initial symptoms after fever, cold, and headache can include fatigue, swollen lymph nodes, sore throat, rash, muscle aches, and nausea. However, it's important to note that some individuals may not experience any noticeable symptoms at all. The only way to definitively determine if you have contracted HIV is through testing by a healthcare professional. I would advise speaking to a doctor or visiting a testing center for proper evaluation and guidance. Please don't hesitate to reach out for support - your health and well-being are important.
