Hi, and thanks for your question.
The symptoms you are describing are not specifically related to an HIV infection or any other sexually transmitted infection (STI). In fact, they are much more common with other things such as common colds and flus. If there is no sexual risk or risk through sharing needles with an HIV-infected person for intravenous drug use, then I would recommend visiting a family doctor or doctor at a walk-in clinic for a general full assessment and discussion.
When it comes to STI testing, we generally recommend testing for all STIs including chlamydia, gonorrhea, and syphilis in addition to HIV since these infections are actually much more common than HIV.
Let us know if this does not answer your question or if you have any more questions or concerns.
