Two questions, the first due ASR symptoms occur all at the same time or due they appear at different times during the 2-4 week window? The other is can a rash unaccompanied by other symptoms be a sign of HIV, no fever , flu like symptoms, or other signs. I did have a slight loss of appetite and stiff shoulders (most likely from worry)? I did something stupid and exposed my self to a person of unknown status. I am now very concerned about being infected. I will be taking a test when I get back to the US. At that time it will be 7 weeks since the incident.
