Hi, thanks for writing in with your concerns. It sounds like you have been worrying about HIV. When both you and your partner have tested negative for HIV, this means that the symptoms that you are experiencing are not caused by HIV because you both do not have HIV. Please consider seeing a doctor about your concerns of ongoing joint pain and nausea; so you can be assessed in person and have any other recommended testing or treatment done.
Let us know if this does not answer your question or if you have any more questions or concerns.
