Are these HİV rash symptoms? I have a small patch of red on my chest like size of a silver dollar and no raised areas--no dots-- just red and and İ have allergy symptoms like stuffy nose. No fever. Does this sound like ARS conversion and HIV rash?
No.
You have a lot of HIV anxiety, particularly for such a low-risk exposure. Just test 28 days after the event to know your status for sure. Symptoms aren't used to diagnose HIV.
